Leaves Curling inwards early veg

JoeGrows89started grow question a year ago

Hello I’ve noticed that the leaves are starting to curl inwards. It has been very hot over the last couple of days with temps in the high 20s and RH any where between 45-60. So not sure if this is heat stress or something else. Should this just rectify itself. Thanks

Das IST eindeutig Hitze / Licht Stress. Also Lampe höher hängen bzw. dimmen und ihrer Dame wird es bald besser gehen.

Too warm buddy. Your leaf temp is too high. A osl fan will help you lower that.

20'd should not cause this type of curling. That's more when its in the mid 30's in my experience. Maybe the medium is also getting to hot though. try and give it some water to cool it down. If the light was the issue I would expect this to be most apparent on the canopy of the plant. From the photo it looks like bottom leaves. Good Luck!

Curled Leaf Tips I noticed a bit of curling on some of the upper leaves. 1st time round I'd had this when my heat was a little high but this is more just the tips than full on taco leaf. Any suggestions on what's up? Also might've overwateres them slightly if that helps 😅

Crumbly fresh leaves (week 2 flowering)About those crumbling leaves: does anyone know what the reason(s) might be? As I've said: semi broke some branches, there's 2 fertilizer tablets in there, and I sprayed them with boomboom spray 3 times in total over the last 4 weeks.

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 👍😳

Leaf damage/discolouration The 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?

Calcium Deficiency ?Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Browning, curling of Green Crack leaves Is this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

Brown spots and yellow tips in flower, started around wk 8-9. Thanks!My 10wk old Auto Trainwreck started showing brown spots and yellow tips @ wk 8-9 but even after up'ing Calmag to each water wk 8 (1tsp/gal) it's everywhere now. It's been 75-50% the whole time- deficiency in late flower? Again big THX to the community - for more than just this.

Leaves curling upwards What 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.
