Hello everyone, I've been trying to find out why the leaves are stretching upwards almost vertically. Some say heat stress or lack of nutrients, others say that the fertilization is very good and the plants are happy.
35 days vegi 18/6 and since 9 days 12/12
What would you say?
Maybe a bit less strong light? they look healty but I looks to me they want to get to the light so they put all there energy in growing upwards instead of puting the engery in the leaves.
