Hi all first post with first problem, My friend has recently repotted the kids whilst repotting he topped them all at the same time and some hve started to droop. They have been under a 300w cfl for 4 weeks including a week of being a seedling, now they are under a 600w hps red spectrum. Room temp is pretty steady at about 29c and 31.7c humidity varys between 35% and 55%. Nutes are canna a+b 13ml of each per 10liters rhizotonic 10ml per 10liters and canna zym 12ml per 10liters.ph is 5.6-6.0 does go up when the feed is left for a couple of days, water is heated to 20c and there is a bubbler to keep oxygen in the water. The seeds are super cheese, easy kush, mamma Mia and power Africa. 1 of the kush looks pretty dead but its been a nightmare from the word go so he will banish it soon. All the leaves look healthy and untill he did the repotting and topping they looked great. Any help would be great thanks.
