Could Miracle Grow Be The Problem?

I would say that after 4 weeks feed them,sparingly at first,whatever soil you use.
Also some strains hate nutes full stop.
You have to be real careful.
I would always use a specific soil that states that its for seedlings and then move them into the stronger soil after the 4 weeks:blsmoke:

Alright thanks a lot, more information on feeding and a schedule and how much etc would be greatly appreciated, I am gonna do some searching too.

I should be going to Lowes this weekend and I will get the Peterson's Plant food.

So the plant food is just mixed in with the water? Should I start at 1/4 stength of what the package says? and just water as normal?

I am probably going to get a different soil while I am at Lowes as well.

i have that MG too. The organic potting mix... so far i like it. I just don't know about feeding and the already time released nutes that say it will last 3 months... I never even thought they really needed nutes.. I mean they would have grown naturally outside with no nutes ya? Or is there something just in the natural earth that potting mix is missing?

natural dirt is enriched with nutes. the plant can also send out roots to find more nutes.

inside or in pots they need food. look at the #'s on the nute package. my veg nutes are 12-6-6 my bloom nutes are 1-3-3. these #'s represent the type of nute. you want the first # higher when vegging. start at 1/4 strength then work up to full strength or even double. marijuana loves to be fed. watch the leaves. if the fade they need food. if the tips turn brown and curl they need less food.

I have another thing I forgot about I haven't done anything to adjust the pH of the soil, isn't MG's pH about 5.0 out of the bag? I really have no way to test pH, but how could I raise it just slightly? I heard baking soda in the water would set a neutral pH. Should I mix a pinch in with the water or something? I also heard Epson salt is good to add to it, should I get some of that, and if so where is epson salt sold?

and one other note, when the plants start going downhill, it is always starts at the very bottom set of leafs, which yellow and droop (or droop and yellow haha), and that continues all the way up the plant, quite fast too.

but I am definitely going to get some new soil, and some plant food ASAP.

Thanks a lot for all the help :).

Oh yeah I am starting some new sprouts in miracle grow potting soil soon. I normally put 2 holes in the bottom of the cup, fill it with MG, water it quite a bit, but usually nothing drains (the wholes are big enough though), and then I wait about an hour, plant the seeds, and very lightly cover the cups with plastic wrap to keep moisture in. Then I just wait for a sprout, and put it under the lights.

Anything I should change? or do different? I am planning on starting about 8 new plants just to experiment around with, it doesn't matter if some of them die, I won't have room for them when they get bigger anyways. The new plants will probably be under 2 4ft floros, which I should be getting ASAP.

You can always pay for ebay items with a money order. It's your choice but it is worth the extra effort! Good luck.:peace:

I am an idiot, and didn't listen when people said miracle grow was bad, it was my first grow, and I bought 2-3 bags of miracle grow potting soil [this was a bit before last summer]. I use CFL's as well, theres plenty of light, trust me, light is one thing I am sure is not the issue.

The entire first grow was very unstable, I had some plants die off, and plants would seem to look good, and then start drooping, and a week later they are almost completely dead... even though the conditions were exactly the same the entire time, consistent watering schedule every 3 days or so, and I did not use any nutes at all, I don't own any, and no plant food either, I don't have any. The water I used was the same old tap water left out for 2 days that I always use to water with.

Temperatures get to about 68-70 when lights are off, and they can peak at 87-89.9, it never ever hits 90. Lights are on 18:6. I have one fan blowing over the plants, all the leaves on all the plants constantly moving, but not violently or anything, this grow is in my closet, which is pretty decent sized, and my closet door gets opened at least 4 times a day.

I am on my second grow... but both grows I used miracle grow, and I am having serious problems... I don't even know if I can blame the soil, I have heard miracle grow is bad... but doable, whereas me, every single plant I have droops at around 20 days in, and then dies, my first grow made it 2 months my first grow was doing pretty well, had some problems, and all the bottom leaves dead, but the top half was doing well, then I tried to flower on 12/12 and a month later, nothing happened but the plant got really sick, drooped, yellowed and died. Plant growth seemed to have stopped, the only daily change was it was more yellow and the leaves were getting smaller and smaller every day.

I had those plants in a pot that the entire bottom was filled with miracle grow, and the top half was dollar general soil, 2 plants made it a lil over 2 months in a mix of bottom half miracle grow, top half dollar general (the bucket was about 1 1/2 feet tall, and about a lil over a foot wide.)

This current grow I am using the miracle grow still leftover from my first grow, they start out fine... not growing as fast as other CFL grows I have seen, but then out of nowhere they start yellowing, drooping and dying. I have had one of my one month old plants die already, and another of the better looking ones is about to die, a week ago it was fine. I transplanted the other month old plant into a bigger container and I used dollar general soil to fill all the gaps, it isn't looking as bad as it was... but its not really growing either.

So pretty much all my plants just seem to start dying out of nowhere, out of all the different sprouts I have planted every one of them starts looking like shit out of nowhere, not to mention they are growing slow as fuck... not just slow, seriously abnormally slow, I had one of my month old plants still growing its second fucking set of leaves when it died, that is not fucking right at all.

I am getting so ticked, I have invested well over $300 into this, mostly on the CFL's and sockets, and nothing will fucking work... one of the things in common with every plant that dies is the miracle.

help would be greatly appreciated.
Your temperature 87.9 to 89.9 f is to high. If ur using co2 u could get away with it. I feel u should lower the temp if u can. Maybe thats one of the problems. Mariujana thrives in temps 70 to 80 degrees farenheit.

I really don't like ebay at all, something about buying used things from random people... if a place like HTGS took money orders that would be awesome, do they?

The last few days it has been maxing at 81... I measure temperatures right near the lights btw, like a few inches away. They drop to the high 60s when the lights are off.

My temperatures aren't as good as they could be... my setup is way up off the floor, and theres very cold air on the floor below, I was thinking of getting another fan and aim it at the floor to mix that cold air with the warmer air in the closet.

but I really haven't been seeing heat stress, I mean as a trend... if heat was the problem I would think all the plants would start looking some sort of messed up to show heat stress... but thats not happening, my plants will grow and the top leafs will always be perfectly fine, and as it grows taller the leafs start turning yellow and drooping, and it goes from the bottom up, same thing on every single plant, there is not one plant that makes it past the 3rd node without having some pretty yellow first set of leafs.

I really think pH could be an issue because of what miracle grow starts off as and I haven't done anything to adjust it, so my pH could very well be at 5.0... should I add a small amount of baking soda to the water and see what happens? I also am trying to find epsom salt... where is that stuff sold?

On top of that they are growing extremely slow, and the nodes are pretty close together.

Thanks for the help :). I should be getting some new soil today, and the plant food, I should have all the new seeds planted today too, theres like 8 or so kind bud bagseeds, should be done germinating. I will probably put 2 in miracle grow, 2 in dollar general, and 4 in whatever new soil I get, and I will try to get lighting equal over all of them and see what happens.

I bought new supplies today and Shultz plant food, its 10-15-10, a bottle of it, says 7 drops per qt, so I will try starting with 2.

I have a pH meter and I will test the pH of everything... but I am not sure how well the meter will work, it has no batterys, and supposedly you just clean the probe and stick it in the soil and wait 1 minute... so far through my testing with brand new Sta Green potting soil, and the same soil in peat cups and watered, were both about 7.0... I tried it twice in the bag and the second time with a "more wiped down" probe moved slightly towards 7.1... at this point I don't think it works... its always at 7.0 and I haven't been able to get it to move real noticably.

is the ph tester green with two metal probes that u stick into the soil. i had one that doubles as a moisture meter, the moisture meter works but the ph tester doesnt.

Nope, its just a pH meter, 1 metal probe... and I really can't get it to work... I got the gauge to move a little bit, I stuck it in the soil waited a minute and watered it and the pH went from about 7.1 to about 7, not a huge difference but it definitely moved... I am going to add a fair amount of lemon juice to the soil later to see if I can get it to move down more, [I am testing it with a old cup of miracle grow that one of my plants died in, not one of my alive ones lol]... but the meter really doesn't seem to work... and the package says theres a switch on it, and shows a switch in the picture, and mentions flipping the switch to get a pH reading... but my meter doesn't have that switch... so I really doubt its going to work, just want to test it anyways.

So I do need a new pH tester, and a moisture meter would help a lot, I wonder if I can find something like that at lowes home depot or walmart.

yeah you can get a moisture meter at lowes for like 10 dollars. thats where i got mine, it is a moisture/ph meter but when i switch over the switch to the ph side i have never got a different reading other than 7 like you are saying. so i dont think the ph tester works but the moisture meter does and it also has a light meter to test where light is the brightest.

I think the probe takes some work to get it to get a reading other than 7... I have finally got it to measure differently at different spots in the soil... I think the problem is my pH is 6.9-7 in all the soil thats been watered, because my water has a pH of 7.0, I don't know, I may just be getting completely wrong reading, but the meter was getting readings in the soil that it stayed firm at the the meter wouldn't budge back and forth like it normally does when you wiggle it. After putting the probe in a glass of water I squirted a lot of lemon juice in it, when the probe was covered the deepest in it the pH was close to 5.0, when it was a bit further out of it, it went to 6.0, strange...

Think I should do anything to try to lower the pH just to see what happens? or is it not worth it because this is a crap pH meter and it could be wrong?

I am a HUGE fan of MG! Have only used two types and have never looked back, MG Moisture Control with the coco used as a medium or just the regular Potting Soil with forest materials and a wetting agent. A bag of perlite and some good "NOT TAP" water will generally do the trick throughout the vegging stage and the flowering, you just have to understand that even out of the bag, Miracle Gro soil still doesn't have enough fertilizers immediately! Understand what type of plant you are establishing, are you a clone guy or just a two time grower that starts from seed? Indica dominant, Sativa dominant...Ruderalis? There are alot of things that most people mess up at in this field, for one, proper watering techniques is it seems is another problem, from what you had said with the coloring on your leaves at that certain time...you were just watering them too much and the ferts in your medium leeched out or "Locked up."
I have made MANY mistakes with MANY types of soils/mediums to grow in, I certainly don't know everything if I did I would be able to tell you what your several issues are with your growing experiences. Closet? How big? Is there proper ventilation? What is the humidity at? Especially in a 89.9 degree closet with only CFLs!? I could say one thing by what you said(brokenhope420) is that you just dont have a proper grow space! Lots of humidity is generally not very nice to many species and strains of cannabis, it makes absorbtion of nutrients too difficult for the plants roots...its sucking up alot of water but only water and salts, everything else is "locked" in the soil and unuseable.
My tip to you for your next grow in that closet:
Continue using the MG as your medium but do your research on the mechanics of soil and how roots work, growing weed isnt a "plant a seed and watch it grow" by itself plant, its "hands on and only learned from experience plant!" A plant is only as good as the soil its grown is, MG is time tested...Many gardeners of all types of species from Tomatoes to African Violets have seen the benefits of using MG and the nutrients they provide! Most likely you have seen a tree and/or shrub that has benefitted from MG!
Keep trying is all I can say...some people do have curses where they can kill plants without even touching them! LOL:clap::clap::clap::clap::clap::clap::clap:

Here are a couple current vegging cycle MG plants with my Indica strain: SuperSchwagg and Sativa strain: Snesley Chocolate((IN THE SAME POT!!))!!:bigjoint::bigjoint::bigjoint::bigjoint::bigjoint::bigjoint:
:leaf:Good Luck:leaf:

I agree, FF Ocean Forest & you will not have to feed your plants the entire vegging period (at least up to 4 or 5 weeks without adding nutes).

Peace out

i feel ya brother, i had the yellowing problem, infact i still do, but, i changed the soil, and they seem like they are snapping out if it.

Also be sure and check your water ph, and soil ph.

the fox farms soil would def. help you out.
