Sensi - Fat beans Choco Auto

So far so good, everything seems to be ok this week, the smell got very strong. sensi's choco automatic seems to be a very fast plant, maybe the fastest to start flowering that I experienced. Plant #1: flowering, filling buds nicely, she has been very thirsty, required daily watering in the past week (about 2l/day). Added some 5-5-7 nutes during all but 1 watering in the past 7 days. Plant #2: flowering seems to lag about 1 week behind #1, has shorter pistils, but the plant is more bushy, has darker colour. Plant #3: seems to have recovered, the gnat attack caused about 3 weeks of development loss. has long pistils like #1, has darker colour and some leaf deformities, but I think all that is due to the early stage gnat infection. Plant #4: least developed among all, otherwise looks healthy and develops bud sites. Done minimal defoliation on plant #2.
