fog in some of those pics above it looks like uve vegged for too long -imo. 400hps doesnt do much good over 2 foot away so u really dont want your plants much taller than 30 inches because u will then have lots of dead space. Short and bushy is best. Ive grown plants that are 16 inches tall that yield as much as 1m tall monsters.
looks like your having fun though!
