Light/heat stress most likely! I had a plant taco before because it was too close to the light. ✌️🏻💚🌿

I had this issue about week 4/5. I figured for me it was heat stress. What’s the humidity and it could also possibly light distance.

Started LST but now plants look a bit sick?
I attempted to do LST but I think I've maybe started too early as some of the leafs started to wilt kinda bad afterwards. Was careful not to break anything. Edges are curling and have discolored. I have a feeling they're a bit short too? Photo from 5 days ago and today.

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

Orange leaves getting worse
What the fuck is going on with this plant? I spotted some nute burn last week so I got advice off here and flushed it out. Once it needed watered again I went with half the recommended nute dosage and now it looks like it’s getting worse. What the hell can I do?

Phosphorus def in veg?
Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.

Necrotic spots
The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

Weird Leaf Problem
New leaves show strange twisting/curling. Humidity ~50%, temps 28-21°C (D-N). Did LST last week—could twisting be due to reorienting to light? Using All-Mix soil, Bio Grow, Calmag. Water left 24h, not pH'd. Some leaf holes caused by me. Flipping soon—help resolve this issue!

How much and how often should I be watering my plants growing in a soil-less mix and 3 gallon pot? I have seen many conflicting arguments. So far I have been giving them 1 Liter every 3 days.

Sick plant, nutrient toxicity?
Few leaves on my plant are beginning to burn, plant was always at least 18” away from my viparspectra xs2000 light set at 50% brightness, so I doubt it’s light burn. Temps are always 73-78 inside the grow tent, this strain apple fritter is sensitive to nutes, happy frog too hot?

Calcium deficiency?
I'm not so sure if it's calcium deficiency, what do you think? Watering 100ml of water minimum. Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free. Should I water her more and add more calmag or is this a different deficiency?
