Day 1 : okay everything is good, I switched light to 400 watt, the ph doesn't move EC stays also at 1.45
I will add some bio grow 1ml/l, top max 1ml/l and biobloom 2ml/l slowly not to break the EC, and also not changing the solution because its so stable in ph damn. trimmed some branches and buds to get into that 50 g club (with 2.25 m2 it would be 120 g). So objective would be around 150g.

Day 2 : I snapped the head of gorilla while wanting to bend it... so I plastered it and lets see how it goes
day 3: gorilla head survived. wow. put more nutrients in it like 10 ml of biobloom and 10 ml of biogrow. EC jumped from 1.4 to 1.9. ph remain stable even decreasing at this point to 5.8

day 7 : the all 4 continue growing. water run low. and ec becoming close to 2. so I diluted with distilled water like 0.5 L just for it to stand till tomorrow (when I change the whole solution). also put biogrow like 3ml a few days ago because thought that it used so much biogrow probably. the snapped branch still lives. and trimmed for a few days. still some buds to trim today. chronic is the fastest maturing. white widow is not getting big. and the gorilla still no sign of real buds.
