Plant Moisture Stress - Symptoms and Solutions

plus its a good idea to autopsy your root system after harvest. you can learn a lot from your success, and failed attempts by the abundance or lack of rooting.

I like to use fox farm ocean forest soil its the best I have used yet. If your on a budget use Dr q's filthy rich soil.

great thread helped alot

You can have TOO MUCH LIGHT?!?!?!
I was under the impression that the more light the better. Is this right or wrong?

Hey U.Ben appreciate all the help you give folks on this site ive read a lot of your posts and have learned a lot from them. I do have a question for you. My plants are in 3rd week flower and are turning a little yellow on the bigger leaves in the middle and top of plant, only where the light shines though and its not from the lights being too close. Also the top leaves feel a little crispy and dry and are curling a little bit...I figured it would have been an over nute problem but im pretty sure it isnt .... what else could cause the crispy feel?? any help is appreciated from anyone..thanks

Crispy feel is from salts that remain after moisture is removed. Yellow leaves? What's the NPK values of the foods they've been getting?

You guys need to read my threads. I have explained a million times why and how bloom foods induces leaf drop. AGAIN, the N value is too low.

I thought it was N. I did read couple of the pages but the thread r too long too read all. what is the best way to apply more N to my nutes? I thought supernatural has alot of N.

I should feed them supernatural aqua grow for the first two week of budding? I notice its yellowing from the top down. is that still N def? There are couple yellow spotted leaves from the bottom. I quickly read thru this thread but i need help asap. just flushed it last night and going to remix the nutes. You mention 1-3-2 are the best for bloom. Should i use the GH three color and mix 1 N 3 M and 2 B? What should my ppm be? they 8 days into bloom and 15-20 inch tall.
?

Top down is N deficiency. 1-3-2 is best ratio for bloom unless it induces premature leaf necrosis, which is what you're experiencing. A wise gardener will give his plants what they require.

uncle ben, thanks for your info. I am kinda new to this. actually i been doing for almost 6 month now and never had finish result. i ALWAYS run into this problem. I had change from H&G aqua a&b, dutch master gold, etc..... finally im decided to go with GH three color. how can i mix 1-3-2 (10-30-20) with GH 3 color? or what nutes should i use? Im would really hope i can learn some good info from da wise gardener. Should i go with Lucas Formula?

OMG! This has happen over night! Yellowing by the hours! what should i do? foliar spray? some one here please advise and let me know what i can use to get more N to my notes. Im currently have two different brand of nutes. Supernatural natural aqua bloom, supernatural super boost. Also have general hydroponic three color. I been following their instruction but i only mix 1/2 of what they say. its only 12 days into flowering. Sucks to see these sexy girls go down! Thanks for ya views

These are three auto-flowering Snowryder that are about a month old.
They're in soil. Nothing special, John Innes #2 from B&Q.
Lighting is a 400w HPS and a few CFLs that I have (200w 6000K, 120w 2700K) that I'm using for side lighting and figured couldn't hurt. They're on a 19/5 light cycle.
I've never given them nutrients.
The temperature is usually between 60-80F/15-25C.

I've been watering them a little bit most days. Been using the "lift the pot method" for seeing if they need water. Oh and like me, the plants just get tap water.

Yesterday I saw some of the bottom leaves on all three getting yellow and decided I was over-watering. Now today the yellowing appears worse.

On a slightly separate note, one of the plants has a yellow spot at the top of its growth that looks troubling.

OMG! This has happen over night! Yellowing by the hours! what should i do? foliar spray? some one here please advise and let me know what i can use to get more N to my notes.

Until you get a handle on plant nutrition, I can not help. I told you what they need, more N while you continue to give them products that don't supply enough N. Cannabis specific nutes suck because they use the wrong NPK ratios for plant health. Likewise, the Lucas formula sucks.
