Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Slight Leaf Edge Upwards Curl?Showing come slight curling on a couple fingers of a couple fan leaves on 2 plants. Also showing on the new forming leaves at the top.

Curled up leaves on day 7I started a plant ten days ago and from the 7th day some leaves started curling upwards.
I flushed the soil one day before planting the sprout and watered it again on day 9. I use the Fecida 600 lamp 16/8 day/night.
Does someone know what could cause the curling of the leaves?

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 👍😳

Deficiency?Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else. I'm using the BioBizz outdoor trypack (BioBloom+FishMix+TopMax) Currently 2ml/L each. Symptoms are shown in the lower leaves. Maybe CalMag? or Pk 13-14? pls lmk
