I found out some weird things on one one my plants.
Some leaves seems to be unhealthy, do you think it's a wind burn ? Or something else ?

Nitrogen Toxicity or anxious first grow?Hi all, what are the opinions on my first grow? Little stunted and I think the "claw" is from the FFHF soil post transplant. Pot is a little big (7gal) for this stage, but I was worried about multiple transplants on my first effort. Is this nitrogen toxicity? No added nutrients.Leaves. Curl down

Why this clawing?Nitrogen toxicity? Or maybe overwatering?
It is an auto plant. Organic nutrition pellets mixed in the soil before germination. When the plant showed first signs of preflower I put a little veg fertilizer. Fewer than the recommended amount. But i watered with 2L of water, 1 timeWeek 2

Moist build up at bottom - overwateredI believe this seedling had too much moist. The soil was moisty when I filled the pot.
Somehow the pot feels very heavy now and seems there is a build up at the bottom. I made some airpockets to the bottom.
Should I wait or take it out and put it into a cup and dry the soil?Week 1

Hello guys,
This is my first grow and I need help. Leaves started curling downwards. I'm not sure whether it was overwatering, underwatering, or needed repotting to a bigger pot. I repotted it today to a bigger pot and crossed my fingers. If you know what's up please help!
ThanksWeek 5

Early growth sick plants - photoperiodPurpling stem, yellowing leaves, droopy leaves - I’m thinking nitrogen deficiency, but I’m not sure if I should add more nutrients or not to my current solution or if I should flush completely. PPM is at 850, and the PH is 6.3. What are your thoughts?
Any GH nutrient schedules?Leaves. Curl down

Leaves droopingLeaves drooping mostly 1 time a day or in 2 days.
Overwatering is probably not the cause as i had times where i only watered it 1 time in a week.
Could this be of fluctuating grow room temperatures?
Temperature during the day could range between 22 and 27 celcius.
Humidity okWeek 8
