Lemon Wonder Auto (Zamnesia), first grow ever :)

day two week three plant 1 shows some discolouration in lower leaves from earlier - now also leaf tips of new growth maybe I shouldn’t have fertilised plant 2 seems happier so far so few fungus gnats watered with neem again :() Thursday: both plants, especially plant 2s growth seems to be back on track or at least continuing Friday: pant 1 which is growing slower and smaller than plant 2 is showing first pistils shall it do that already? ++ If someone knows when to switch the light from veg to bloom setting?
