I'll take all the advice I can get.

they look really bushy and healthy , there does seem to be signs of heat stress in the second pic but its not that bad . keep up the good work

Is it just me, or are the leafs have dis colored patches?

if so, do you have any bugs living in your pots? other than that, there looking healthy

Yeah I think I fixed the heat prob and I think the spots on the leafs are because they didn't have enough nutrition, thanks for the quick replies.

mmmm i love bushy plants...

lookin good mak keep it up
