I am on my 5th LR2 cabinet grow about 1 week behind you using 250watt HPS and your plants look great! Maybe you don't have the room, but why did you not put them in bigger pots? You seem to be all over the nutes, but my strategy has been to put them in bigger pots early with Foxfarm Ocean soil to give plenty of nutes and avoid any rootbinding stunting. Maybe I'm wrong, but they mature so fast that I am trying to give them every incentive
to grow big. They mature so fast that any setback will decrease the yeild. I put them in a 2 gallon pot at 10 days. Probably not add nutes for a month. Previous grows seemed to be stunted when I used smaller pots compared
to other grows I have seen, but I was not as serious about nutes compared to you. I was always to afraid of nuts burn like so many have encountered with LR2. Great grow thread. Keep it coming.
