Green gelato auto 4x

Day 22: light 100%, 50 cm above tops ( was 45, but Nr.4 tops didnt like it). All girls showed preflowers. Nr.1 is shortest pheno, verry bushy. Nr.3 and 4 are tallest ones. Girls showed some deficience(like Mg or N def.) ~7 days ago, probably because of underwatering in big pots. I watered 0.5l every 24-36 hours, but last 7 days i start with 1l every ~36 hours and problem is gone. Anyway, there wasnt problem with slow growth, progress is still great. Day 25: Burned tips again, these girls grow really fast 😳 🤦
