update

2nd day since I put them into 12/12.
I tried feeding them 600ppm into the reservoir and the nutrient level kept increasing. They seem to not like very much food, or maybe it's just one of them in the system that doesn't like it messing up the whole levels

right now it's at 525ppm and they seem to like it
yesterday i took my last clone off of Spracky, who doesn't really resemble it's name anymore at all.

pH seems to want to stay around 5.9-6.0
I'm worried that they might get too tall during the stretch for just a 250 watt light

heres some shots
Does the last shot even resemble a female preflower at all?
