Overwatering or heat stress? Something even worse??
NumbThumbGardenerstarted grow question 4y ago
Leaf curling? Only on the very outer edges, and certain leaves. Light was 13” up, but I moved it to 28” decreased humidity from 70-75 to 50-60, and slightly increased air flow. I noticed two days ago, they seem to be just barely better. Overwater? Heatstress?

Nothing to worry about, fairly normal behaviour for young cannabis leaves, nothing that is going to cause any problems.
You may be over thinking this slightly......

It’s just an early leaf deformation thing. Nothing to be worries about. It will grow out of it— plant looks great

Hey guys, one of the main symptoms of heat stress is when the tips of the fan leaves start curling upwards; they do this to protect themselves from dehydration. They also look dry and wilted. Most likely, it's the heat that's to blame, which rules out any possibility of a nutritional deficiency.
Nothing to worry about, it always happens to me in summer; you need to increase air exchange and boost internal ventilation. And BE CAREFUL, if the substrate dries out too quickly, it's not that the plant is absorbing everything, but that it's evaporating, so WATCH out for the ppm levels.
This is super beautiful. Great job, keep it 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 appreciated

Leaves are drying up and turning yellowHello,
Something bad is going on with my Hulkberry plant. I think it might be due to giving it to much fertilizer.

Strange leaf deformationHave these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though

Light StressHad to move my plants to a new space and under a better light, can see taco type appearance to leaves, I'm assuming this is due to light stress?
I've lowered the plants and also turned the light down a little until I know what is going on.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.
