Leaves are curling up that way due to heat. You can see this with the way it happens less so at the bottom.
The tips are damaged either from nutrient burn, or because of the extra water transportation due to the high heat (basically it drinks quicker to combat the hear and can cause nute burn by eating faster than usual basically)
If you can dim your lights do that otherwise I'd suggest you raise your lights.

They look great. Really green. Probably maybe too much nitrogen for the flowering stage.
I would cut the nitro and focus on blooming nutrients from now on
Cheers 🤙

Spotted crisp leavesWhat's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.Leaves. Edges burnt

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.Leaves. Curl up

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown.
This starts at the tips of the large lower leaves and spreads quickly to the whole leaf.
Also modest edge curl.

Phosphorus def in veg?Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.Leaves. Curl up

Clawing/Yellowing? (def not over watering)Anyone want to take a guess at what's going on with the clawing/yellowing? Very highly doubt it's over watering. It's slowly been showing more signs of it the less I water and I'm pretty heavy on perlite. Also using the lower recommended amount on the nutes.Leaves. Curl up

Nute Burn? Or something else?I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciatedLeaves. Curl up
