These are the new kids on the block, 4 in back Skunk 1 the 4 in the front OG Kush, this is my normal routine I start things in a styrofoam cup then transplant to 5 gal smart pots after dusting the roots they go in bags with FFOF soil and given only cal-mag, liquid seaweed, and vitamins till usually week 5 then go right into flower schedule sometimes I will have to feed before that but rare. I am also pushing the limits on getting root bound I would have already transferred them but we are dealing with hurricane Ian say a prayer for us down here and along the East coast it’s going to be ugly.
Looking good Cake, I don't believe the temp change would have really made much of a difference in the root development. When plant is young I struggle to keep the RH up above 65% I am convinced that what we do early in the plants cycle as far as root development is detrimental on how that plant grows. Even how we water them.
