Kind of looks like it could be both light stress and calcium issue.

Heat stress? (1st grow)
Hi, Here we start with the problems. The leaves are curling up (little yellow), not much. I've looked that up and it's probably heat stress? -My led lamp is at 55 cm -The plant receives 500 PPFD Also a friend told me to water it nearly 1l, if that's the case I was giving way less

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Nitrogen toxicity?
This plant hasnt had any liquid nutes since been tranplanted 3 wks ago, i did however lightly foliar feed 0.5ml/l of bio-grow 1ml/l bio-heaven and 1ml/l cal-mag mixed with 1L spray bottle used over 1 week. My other plant looked deficient and bounced back. Could be anything else?

Does the curl here (pic- Day 10) look like mild heat stress? Temps hover around 23-24°C (~75°F). RH ~ 65-75%. Water pH'ed to 6.5. Soil runoff tests @ 6.4-6.5. She's due for a drink tomorrow...any experts feel like throwing me a tip? Am I just overreacting?

Leaf tips curling on top
What’s causing the leaf tips to curl? I moved the light away and reduced the power to 75%. Please advise on how I can address this. Looks like her growth has changed, a bit slower and a bit lengthy.

Organic soil 0.1-0.1-0.1 60% soil 40% perlite soil is pretty damn dry on top
The girls seem to be doing ok, little bit of curl up on some of the leaves, which indicates I over watered, humidity is usually 40-50%. I water 1 time per day with a mister, it's only been last few days that leafs curl up. Is it time for nutrients?. They are 10-11 days old.TIA

What’s Happening Here With My Leaves?
Not sure what’s going on here. It’s happening to 3 of my plants and I’m not sure whether its good or bad. I haven’t watered in 3 days so I don’t think it’s overwatering because it just happened today.
