Yes your temps are aggravating whatever problems you have and you NEED to lower them

You could have a nitrogen overdose, looks like it to me, totally possible with organics... plus remember that the plant is not going to be growing as rapidly under heat stress like you are putting it through and its nutrient needs are different. Whatever it says on the bottle, that's for a rapidly-growing plant in GOOD growing conditions, like in the 70-80 degree range. Just like you don't want to overwater a plant that is sitting on a cold cellar floor and not growing or transpiring much moisture, you don't want to overfertilize a plant that's in a freaking coma from heat. According to the guy who runs the local grow shop, the magic number when metabolic processes start to break down in cannabis is around 95 degrees... enzymes and hormones and receptors necessary to plant growth and cellular function simply cease to operate properly... remember it's all chemical... remember hich school chemistry class? Did you do any of those rate of reaction expreiments? All temperature dependent. Keep that in mind.

You need to thoroughly flush out your soil.

Taking clones right now is practically destined to failure since the plant is already stressed so badly and you have to prep mothers by WITHHOLDING nitrogen, not overdosing them with it.
stinkyattic Reviewed by stinkyattic on . Look, my leaves are curling under and dying. Please Help!!! My leaves are curling under and one of them is crispy and already dead. I am thinking of salvaging some clones off of it before it goes completely, but hopefully I will be able to save it. Yesterday, I checked the pH and it was at like 5 so I just did a rez change because it needed it anyway. The nutes I use is in the picture below. The temps are high, like 90, but it has been for the past 2 months cause its hot here in the Bay, so I'm quite sure its not that. The pH was corrected to 6 and I Rating: 5
