are my plants normal and good

just been looking on youtube at plants around 30 days old and they always seem to be more bushyer than what my are i have topped them once nd dont plan to top again. can somone ell me if they look ok the one closest is the youngest 29 day old red dwarf atomic and the one ferthest is a 31 day oldheaiian mawi wawi

soz about the pic being wrong way forgot to turn it

with only that pic to go by it looks like you need more light closer to the plants, they have stretched a lot.

thats what i thorugh im about to put them under a 600w hps light how close should i have it

keep light as close as you can, without burning top of plant(use your hand to judge the heat level at canopy height) happy growing
