Overwatering?
TheeLemon
started grow question 4y ago
Can anyone confirm that this curling up is due to overwatering? I don't see any yellow leaves that would indicate overheating. But I read it could also be a nitrogen defeciency? One pic is upside down, I wasn't stoned taking the pic, honest 👀

It could be heat stress. Doesn't look like a N problem. Also might be the roots have outgrown your pot.

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.
Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing. I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"

Bud rot?
Can leaves be an indicator of bud rot without seeing actual bud rot? Day 65, day 35 of flower. Looks bad...question really isn’t what I can do from here, I think I need to ride it out and harvest early. But is she a lost cause or likely candidate for bud rot?

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Why are the sides curling up? Question not about them pointing down but only about the sides curling up and very small brown points
What is this? Sides r curling up. Day temp didn't get over 23 degrees night temp is +- 12 so I don't think she got too hot. Points bit yellow Saw this yesterday evening too, today at 1 plant a little bit. They're probably pointing down because of the low night temp so that's ok
