If you are seeing new growth since the transplant then I would say it is safe. As a general rule for me, I wait a minimum of 3 days and of course some plants need a little longer, but new growth is a good indicator.
Plants doing good my main one unknown strain named chiller now because of their affect I got from it 9 1/2 in tall topped once. Trying to post pic but something keeps happening can't upload
Yeah a cfl bulb busted on it maybe the mercury in it? ? Do I just let them be I've cut two of the more damaged one's the plant itself is doing good after water and feeding it last night at 12 it's grown 2 in
Most indica and hybrid cannabis strains will stretch 2x-2.5x (sativa's can stretch up to 5x) when placed in flower. I recommend when your plants are 18"-20" tall you place your plants into flower.
