Plant Moisture Stress - Symptoms and Solutions

Sweet, I just changed out the 1000 for the 400. I never would of even thought about to much light.. Heat yes light no... I can't thank you guys enough for the help and the information. Looks like I just found a new place to call HOME

Oh I also added some more water to lower the Nute. This new system has been a new experience. Again like a new dad LMAO

Thanks again

what is the conversion you are using to get your PPM?

PPM is derived off EC and there are at multiple conversion factors used by different manufacturers of meters.

I'm not saying this is wrong but, why do you jump around on your feeding levels?

do you mean 3X and 2X per week? If so, why did you go from 3X to 2X? I usually up the number as the plants grow.

We water by hand once a day, now. We went from 3x, to 2x, to now once per day. We jumped from around 500 to 1000 or more PPM which I think burnt them. We just flipped to 12/12 and are weaning off Veg Nutes, going to Flowering Nutes at around 600 and then pumping upward to maybe 1200 we will see what they can take. Also think overwatering might be an issue now, some algae grew, which is an indicator, and some leaves are still cupping.

1000w is like a nucleur storm to those young little girls. . You gotta wien them to that kind of light and nute.

I have used 1000 watt lights to root clippings. If they are spaced far enough away they wont burn the plants. If they are too far away they won't be enough for that matter...

Thanks for the reply. would a 400w be better and less nute?

I would recommend getting a light meter. How else can you know exactly how much light your plants are getting.

Hello again,
I checked the babies when I woke up and the puffiness of the leaves has gone, the leaves are pitched up towards the light and they look happy.
What I ment with the "3" is the pump floods the table every 3 hours.

I am going to go and buy a light meter and a dig PH meter. The person I bought the Nute from gave me a DIY sheet for " size-growth-clour-etc" but was just a guide line, so I needed to add some water anyway due to usage.. I hope I did the right thing..... Again they look happy for now

I cant tell ya how Happy I was to find this site...
Thanks again

Hey Uncle Ben. I would really appreciate if you took a look at my thread and gave me some advice. I have read and read and read, and you seem to be one of the most knowledgeable growers on ROI. Any advide from you would be extremely appreciated. Thank you very much man. Have a great one. I want this to be a somewhat decent first grow.

Appreciate your time.

I need help ub.I've read alot of your threads and advice,and figured who better to help me help my plant than you.
I have a 10 day old seedling(from seed).I started it in a jiffy cube,once it popped out of the cube i transferred it to a 10 litre pot.
It is just starting it's second set of leaves(first set of three leaves).I haven't feed it anything but water yet(still to young for nutes yet).I am using a neutral organic soil as my growing medium.Yesterday i noticed that the first set of leaves are beginning to droop,yellow,and black spots are forming on the leaves.I read one of your threads about over/under watering and think that i may have over watered it.Is there a way to reverse this?If i don't water for a little while will it bring it back,or is my plant done for?I will include some pics of my plant in hopes you can assess the situation(the pics aren't the best i know!!)
Thank you.

PIcture quality is crap, but it does appear to be over-watered. Just give it some time without water and it will begin to recover in 2-3 days.

Will the black spots fade away,or will they just die and fall off.There only it's first set of leaves so i'm not too worried about them,it's the future of the plant i am worried about.It's a feminized big bang seed from ghs,and since i paid for it,i don't want to kill it.Does the peat in the jiffy cubes retain moisture longer than plain soil?

EDIT:

I'm removing my post (my plants likely overferted & overwatered - asking what to do now if diagnosis correct) since I was in panic and I quickly posted lacking info on an issue that has probably been covered many times on this thread.

I will do some research now before posting here to be sure I'm not wasting your time - sorry & thanx

The black dots are an expression of stress, a symptom. It is the precursor to leaf drop. Just like if you were to lose a leg to gangrene, the gangrene would not affect your entire limb at once, it would start small and the disease would spread - same drill here.

A 10 L. pot is too big of a pot for such a small plant. Jiffy cubes are too small, they restrict/stunt root development. You're really off to a bad start. Did you read any books on plant culture or is this your first stab at growing anything?

In the future, soak the seed for 12 hours, sow it in a tall 20 oz styrofoam cup, at least 6.5" tall, that has holes burned in the bottom with a hot icepick for drainage and when you feel the plants may be getting rootbound then upcan to your 10L. pot. The seed's taproot (radicle) is already 4.5" long by the time the cotyledons pop the soil's surface, don't restrict it.

Your plants are yellowing which means they are deficient in N and other minerals.

Good luck,
UB

Thanks for the reply,
Will the black spots continue to spread through out the plant?It is my fourth try.First with fem seeds.Others were just bag seed.2 males and a hermie so far.Was hoping for better luck with this one,but like you said,seems to be off to a bad start.Will it recover,or is it over for poor seedling?I was going to start feeding it nutes next week at quater strength(book says not to feed seedlings for about 2-3 weeks after germination).Should i start sooner.I did soak it in water over night.It is also first time i tried the jiffy cube.All the other times i just planted it straight into the soil,and although they turned out to be male(or hermie),they still grew,and looked better than this one.
I do have a few books that i use to reference(marijuana horticulture by jorge cervantes,and the cannabis grow bible by greg green).

Thundernuts, you need to learn what makes a plant tick. I gave you my thoughts.

hello there im havin major problems. my plants in week 4 bud are yellowing lookin rusty on leaves. most of the yellow is coming from the top down. i thought it was lack of food so i up it to 1500 and no change. Its an old strain of kk could it be the plants themselfs? its been doin this for years and ive tried everything. Growing in hydro and everything is perfect till week 4. I veg 5 weeks the plants are about 5 ft tall and 4 ft wide. Any sugesstions

Uncle Ben,
I have two plants in veg for about 3 weeks and have noticed that two lower leaves are not as developed as all my other ones. Is this normal? To me, the leaves look like they are hard and not the nice full fans. Does that make sense? Your thoughts?

Can't give my take without more info, mainly NPK values.

I have attached some pictures for you. Please ask any questions you might have. I have them in Fox Farm soil, only used grow fert(very little) as a spray on foilage and have them under a T5 light in a silver addition grow room.
