To fix it, go to quarter strength and the extra run off should start rinsing the excess nitrogen out of potter.

leaves dry and curling up
Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

Leaves are curling up
The sugar leaves on one of my plants have curled up, I was wondering if this could be a humidity issue or maybe a temperature problem. Can this affect the plants yield as it is approaching harvest time.

Upward curl
Hi Breeders, Elizabeth is growing well, but the bigger leaves are curling up at the edges. I already increased lamp hight and lowered to 18/6. Is it air humidity? Or too much water?

Why are my leaves canoeing?
Noticed that the leaves on one of my plants is started to badly canoe. This plant has been lagging behind the other the whole grow (different strain and provider). Not sure if this is a nutrient deficiency, exceedance, or something else. I flushed both plants.

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 appreciated

Has anyone else heard of using epsom salt with gallon of water for magnesium and sulfur issues? I'm told you can water them or spray them during lights out. I've had some issues before with magnesium due to soil pH recommended by maker didn't follow it I later corrected it pH
