take off lower growth on most mature? still high RH but low indicated in the tent maybe 20-30% since its still winter. run humidifier or no? When below 0C? any advice on that front would be great. Edema is there. trying to water less and let them really dry out first.
environment? over water? poor drainage? they look good. late jn the day they droop if it's hot etc. airflow? your light seems underpowered how many of those tripods do you have?
I would guess a little to small to transplant up. Wait for the second or third true leaves. Those are jus Cotys. How good is your drainage? I try to follow this. https://thehotpepper.com/threads/growing-hot-peppers-guide-faq.46361/
I am using a Mars ts600w for comparison. I can't put the light 6 inches above plants they would probably catch fire lol. I think yours a stretching light intensity low. you might be able to get away with starting one single plant on one of those tripod led ones. Even one plant is probably too...
Edema set in pretty hard lately in the bigger containers. No more water for those. I have a hard time not overdoing it as a newbie. External outside rh has been close to 100% but in the tent with no humidifier running it will go to 20-30% with lights on. just readjusted timer for 18h.. sleeps 6h..
How about a Brita longlast? https://www.brita.ca/wp-content/uploads/2021/06/Longlast_PDS_2021-06.pdf | I worry more about the chloramine vs actual chlorine.
