These girls seem to be a week behind where i would expect them to be. They are slowly getting there i have upped the light to 660w and introduce some extra co2 one of them bag things not sure if they work but for £3 thought it was worth a punt.
I changed the res on 21st and i have topped up twice since with mild nutes 7ml of A & B to 10 liters of water and 5ml of buddy.
EC in the Res is stable @ 0.8 ph was 6.2 this morning.
Temps min is 20C and the max was 26C forgot to look at the humidity but will be low always is this time of year. The white hairs are starting to push out so im happy with that.
