Usually a sign of over heating or lack of air movement. However, I have seen the odd plant grow like this for absolutely no reason over the last 40 years.

Yellowing between veins on 3 of 4 plants, and curled tips - 27-29C in tent - Just heat/light stress or something more?
Only on 3 out of 4 of my girls, see 1 pic of sad girl and 1 pic of happy girl. Does it look like heat/light stress to you or something more? I was running my LED 45 cm below the lights dimmed to provide 20-30k lux at plant level. Just now raised to 65cm, lux 20k.

Brown spots, serrated edges curling up - calcium deficiency?
This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up. Is this just a straight calcium deficiency?

I am getting leaf curling and yellowing on my 3-week-old Hulkberry plant. I suspect nutrient burn, even though I am using what was recommended by my local grow shop and also RQS's website. I have reverted to water only and raised the light higher. Anything else?

Surplus or deficiency?
Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

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"

WHAT IS CAUSING MY LEAVES TO CURL? (Day 64 pictures)
The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏

Leaves Curling Up
I've seen some weird leaves on the Moby D... they look curled up and most of them have only 3 leaves. Can it be related to the LST ? Should I be worried ? Thanks for the support !!!
