exo is very interesting to grow, the livers and psycho have hit the gound running with perfect leaves but the exo is a different story, at some point in mid stretch it seems to just go superhungry and this is what it is getting to keep the leaves healthy.....one day 3ml biobiz grow plus 3 ml/l bloom plus 1.5ml/l magnecal and iml/l canna trace minerals, I shit u not, the next day gets compost tea, the following day more biobizz of if they need k its canna terra flores at 4ml/l....the cunts don't seem to need strait water in early flower, and they can still run a sneaky Ca def even with this level of nutes.......don't treat psycho or livers this way they will burn
