Plant Moisture Stress - Symptoms and Solutions

I appreciate your patience with me. Ill get this figured out.

Hello UB,

I am glad I found this thread and hope that you can help a brotha out. I recently have fall into some problems in the last 48 hours and it's scaring me...

She was having yellowing of the lower leaves so I basically flushed the soil 2 weeks ago, added some dolomite lime and started giving her nutes again with some light foilar feeding. It was BMO grow it green (5-2-5) and I was dosing about 1/3-1/2 ounce to 3 cups of water. She seemed to be recovering from the N deficiency until yesterday. I think I was getting a little too happy with foilar feeding and possibly had 1/2 ounce nute's on the last watering. She looks like this now. All I know is I see tons of problems with my plant (heat stress, nute burn, deficiencies, etc) I need to get this under control asap and know that your wisdom can help. I'm growing in FF Ocean forest soil with BMO nutes under a 150w HPS.

Hmm about 2 days ago the soil got really dry and she wilted a little bit, but I fixed it soon as I checked on her. Possibly the wilting to over nute is my problem? My mistakes have led me here and I need to find the road to healthiness.

Thanks for the help and hope to hear from you soon


Edit: I just flushed it with 6 cups of purified water and lowered her 2 inches. Hopefully this was the right action to begin with, but at least I know that the medium is clear of excess salts now and that heat stress has been lowered (peace of mind)

1. It's time to summon a priest:



2. Don't attempt to grow again until you understand what makes a plant tick.

Better luck next time,
UB

Ahh well I don't think the miracle is going to just happen and I'm going to keep this one going. She was looking very healthy 48 hours ago and this is my 3rd time growing organiclly in soil. So I may have a lack of experience compared to you, but I'm self sufficient on what makes a plant tick. I tried to include what I've been doing in my last post to get an idea of what's happening, but I guess your wisdom is of no use to me... I guess thanks for nothing.

I'm changing forums soon I think, every fucking question I ask I get the dumbest fucking answers. Why is it so hard to relate your knowledge to my grow and give me a hint of what direction I should be going. Whatever dude

He did exactly that, the plant is gonna be a bitch to save and an experienced grower knows when to fold and start another grow, learning from the mistakes and not repeating them.

I was gonna say the same thing he did but decided to wait as it's UB's thread

Good Luck

hey thanks alot! it really helped out. im a first time grower and i was having the same issues. i started to think it was some type of a virus on the leaves. thanks again.

stillnrmr

Its hard to give nice advice to someone who clearly doesn't know how to grow a plant. Im guessing your first two grows were both failures, which this grow is the same thing judging by the pictures.

Are you growing that plant under one incandescent bulb or something? She is incredibly stunted.

Re-read the faqs, or read them if you never have. Buy the necessary equipment to grow healthy plants, and you wont have to worry about people busting your balls. I promise you, that you'll get even worse treatment if you posted those pictures elsewhere.

We can only go on what you have done and shown us. It doesn't look like you are, as you put it, self sufficient on making a plant tick. (your pics as a reference)

Maybe you should re-read the post. He gave you great advise. Throw the plant out. Start a new one.

Have you seen fight club? You are like the guys who are told to leave because they are too young, too old, too fat, etc and they just leave... The other set of guys where told the same thing but stood in the front yard waiting to come in for days. then they got in...

You may be making the biggest mistake of your growing career here.

Read this post twice for better comprehension. Seriously, even good readers can benefit from re-reading, so this isn't a put down.

About the other advise to learn to grow...
Get a book on container gardening and grow a tomatoe plant that is really robust looking. Once you have done this, you will see things different and hopefully realize that the advise here will leading to predictable outcomes. There is a science to this and if you can understand that then develop your senses to read your plants (this is partly an art), you will be a great grower. There is no rush to do this, but don't bitch at people who are pointing you in the right direction it just looks stupid.

I'm wrong, your right. Ok

Time to get high and not think about it.

Have a good one folks

Here's a pic from my last grow, a success? But that wouldn't be possible because my lack of knowledge, right...

I do things differently. I suggest trying out something a bit different (you know the old saying doing the same thing and expecting diff results is crazy...)

Try getting high and *thinking* about it

do you have a pic of your grow before you harvested? A bowl of buds is good but I'd like to see the actual plant. How many watts did you use in how many square feet and what was the total dry weight of the harvest?

I'm sure you are doing some things right, but like most of us maybe you have some room to improve. But, if you are not into having people point out errors you may be in the wrong thread...

Right on dude (JJfoo), we all make mistakes and no one can grow perfectly. It's a skill to get everything right on. This is more of a hobby to me then a lifestyle like many I see on the forums. That is why I always keep it small and discrete.

Btw, my plant has improved since I last posted. The pic I posted was right after a 48 hour period of me being gone and her health dropped QUICK. I took the right steps to correct, but as usual, you guys are full of no advice. I mean you may as well keep your comments to, "figure it our yourself," because that is what I am always told. I know sometimes you guys get tired of repeating stuff to the noobs, but come on now I wasn't asking a retarded question like, "whats a plant..." I post in like 3 different areas of these forums and it's interesting to see where people actually chime in with USEFUL INFO to a fellow grower. I'm persistent and I know when to throw in the towel...

I keep it pretty simple, organic ff ocean forest, blue mountain organics nutes, 150w hps, some cfl/fluros. Project is in a small closet with a fan on the girl and another ionizer fan ventilating the closet. I usually keep get them around 2 feet so I'm in 1-2 gallon pots (i'm about to transplant this one into a 3 gallon bucket when I get a chance) I experiment with nute doses and foilar feeding and sometimes I do make mistakes. It's not exactly the easiest to figure out how much nutes your plant needs. That is really where I would appreciate the advice.

By the way, I may sometime come off as an asshole, but no disrespect to any of you. We are all here for the same reason

I'll drop a few pics of my last grow, white berry. If you haven't heard of that strain then check it out, stuffs reallll good and works super well in SOG setups.

I'm not giving up on my Moby Dick for at least another 2 weeks. So instead of telling me I suck at growing and I should quit and research more (i've done over 30 hours of research, I DO READ) help me get this girly back to healthy standards. I am currently in flushed soil and corrected the heat/ventilation issue. Back to that fun game of nute doses and making sure she doesn't acquire any deficiencies. This is the hardest part for me.

~Peace~

You asked for help, here's the skinny although I don't have alot of patience when it comes to teaching basic plant care:

Why? If you have premature leaf drop there is a good cultural reason for it which I covered in my ditty. What's your definition of flushing?

... added some dolomite lime

Click to expand...

And how's the dolomite lime supposed to help?

and started giving her nutes again with some light foilar feeding.

Click to expand...

So you reached an elemental saturation point with both foliar feeding and root feeding and then added dolomite lime to boot? Sounds like you're trying to push your plant, which has pushed it to the edge of its grave.

It was BMO grow it green (5-2-5) and I was dosing about 1/3-1/2 ounce to 3 cups of water.

Click to expand...

1/2 ounce aka 1 TBLSP. per 24 oz. of water is enough to fry a fish. That amount will be fine for 256 oz of water. I doubt if you have any small roots or roothairs left. That plant is toast, it will be stunted forever. Accept it and move on.

She seemed to be recovering from the N deficiency until yesterday.

Ya think?

I think I was getting a little too happy with foilar feeding and possibly had 1/2 ounce nute's on the last watering.

Bingo, Father DoItRight has received your confessional with his blessing.

Hmm about 2 days ago the soil got really dry and she wilted a little bit, but I fixed it soon as I checked on her.

Click to expand...

How's that? By using a little water, not enough to get good run-off? Why did you let the soil dry out? Do you water until you get a good runoff? This is basic stuff.

Possibly the wilting to over nute is my problem? My mistakes have led me here and I need to find the road to healthiness.

May I suggest a book on general plant culture? Or, if you must, buy Mel Franks MJ Insiders Grower Guide, it covers the basic principles that apply to ALL plant material very well. It will be your shortcut to success.

Now, you have 3 choices:

1. Shit can that plant and don't attempt to grow again until you've removed yourself from cannabis forums and read some good books on general horticulture, or,

2. If you really want to save that pathetic thing, repot into fresh soil gently (inspecting the health of the root system) and bury the plant up to its first leafsets to induce rooting along the "trunk". Add some Osmocote, nothing else, (sorry, I don't trust you, yet) and let nature take its course. Downside the size of the pot. You must size the pot with the transpiration dynamics of the plant which is controlled primarily by the leaf area and quality of the root system. It does not require a 3 gallon pot now. My avatar does, yours doesn't. The quickest way to screw up a plant is to give it something it doesn't need/want/require.

3. See the latter part of #1.

Good luck,
UB

Thats some funny shit.

But on another note... are you saying that u shouldnt have a small plant in a big pot?

It invites root rot due to a very slow wicking off of excess soil moisture. Small plants need small pots.

So does it matter when i plant outdoors (my 1st time) ?

I have heard ppl talk about pots that the roots can grow thru. Would you suggest something like that. Or should i veg them big in my hydro then put the in some big holes with good soil ?

Are you going to native soil outside, and if so what is its structure like and pH?

one love one heart

From what Ive read... I should dig a big hole and mix the native soil with... well there is alot of different opinion on that part. I am trying to figure out what it is that i should mix in. Any suggestions ? I will be growing Durban Poison.

It is the front range of Colorado, so its pretty hot and dry and windy at times.

I will find out the ph of the soil. We will plant near an irrigation ditch where there are clusters of trees to help shade. The property is big and very private. So we can do pretty much what we want.

1. Over-fertilizing - the most common cause of leaf cupping aka leaf margin rolling, leaf margin burn, and leaf tip curl/burn is the overzealous use of too much plant food in relationship to factors such as plant size, vigor and rate of growth. The first unit of a plant to show moisture stress is the leaf at its margins and/or tips, reflected by margin rolling (cupping) or burning. Sometimes copper colored necrotic spots show in the leaf also. A hard, crispy feel to the leaf frequently occurs as well, as opposed to a soft and cool feel of a happy leaf. When you have a high concentration of salts in solution (or in the root medium) compared to lower salinity levels found in the plant’s tissue, water is actually drawn out of the plant across the root gradient in order to fix the ppm imbalance. IOW, this is a natural, osmotic response that serves to equalize salinity levels on both sides of the root’s epidermal gradient. Back off on the amount and/or frequency of plant food. Too much plant food can also burn the roots, especially the sensitive root tips and hairs, which then creates another set of problems such as nutrient deficiencies. A note for the bio folks - as soil dries, the concentration of the remaining salts rises further exacerbating the problem. Leach (flush) your pots once in a while to get rid of excess salts.
DID NOT REALIZE MY MIRACLE GROW PERLITE & PEAT MOSS WAS ENRICHED WITH MIRACLE GROW CRAP. I AM SEEING THE COPPER COLORED NECROTIC SPOTS ON MY FAN LEAVES. & I USED FISH FERTALIZER (1TABLESPOON PER GALLON) TO WATER TWICE PLUS WORM CASTING TEA. THIS MAKES SENSE. I AM USING DISTILLED WATER FOR THE TIME BEING AND WILL "FLUSH" WITH IT NEXT WATERING. THANK YOU
