Looks like it has a little heat stress, but still very healthy looking for being in high heat all week.

Yes light heat stress but nothing to worry about. Mother nature has always taken care of herself outside.

Leaf damage/discolourationThe yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Burnt? PH lock-out? too much Cal-mag??What do you think is wrong with this plant?
All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

The leaves are curled up, it's hot in the room these days, I guess this is the reason. Plants growing fast anyway, humidity between 48%57% but I'm worried because of this leaves problem. Should I ? I do my best to cool down but can I do something else ? Mist the leaves ? Thanks !Week 2

Leaves curling upwardsWhat could this be?
I consider too intense lighting, could that be possible.
Just transplanted a few days ago into these 1,7l pot's. Since it is the first time i use the The Mars Hydro TS 1000 for flowering i think i might have given the plants too much light.

Necrotic spotsThe last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

Serrated edges curling upWhy are the Serrated edges curling up. I took humidifier out last night and the leave look less dark. Rh is now bt 55-60. Mars hydro sp2000 Light is 2 feet above and on 50%. Do I need a fan? The air being sucked in is chilly but not directly blowing on the plant.

Starting TrainingI'm currently worried about my older plant set that seem to be constantly having the leaf edges curl and seem to be a little droopy and a little too dark green. Also I feel like I should be doing some sort of training. I would love to have some feedback on what you all think. ✌️5y ago
