Heat stress? Light stress? Nute burn?Hi y’all
Since my girl started to flower the top leaves near bud sites have this weird cupping downwards look. I doubt it might be a nute burn since I already gave her a good flush.
I think the heat might be the main issue (86-87degrees during day).
What do u think?

Why are some leaves curling strangely?Hello everyone, the problems begin unfortunately.
Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.

Seedling curving down and turning pale greenThe leaves of my two seedlings are curving down and it turns a little bit palw green. I think I overwatered the first days, but now it looks like the substrate is really dry (I didn't watered the last 2 days) but I'll wait a little more. So is it the problem or I miss something ?

Nitrogen toxicity?It has a weird leaf curl. The ends are pointing straight down on some leaves. Also, a little twisting. Maybe some dark leaf veins. I’m reusing some soil from my last grow that I had outside in a huge pile all winter. And I only put .25 tsp per gallon of Big Grow last watering.

Leaves suddenly droopy and curled at the tips, although look a healthy green. Doing DWC. Help please!They look overwatered, but this is DWC and I'm not top-feeding. Not sure what is going on as the leaves, themselves, look a healthy color. Pics from 3/25 show this, and I have detailed info in my diary. I have tried dropping humidity down (was keeping up for VPD). Thanks
