Great advice so far ...I'm gunna add to what Rick and ChAs have already said. Listen up !!! Improve your substrate/soil, add perlite, to increase air flow to the roots ! I'd repot and drill a bunch of holes in your pots to increase drainage. Use Recharge or similar product. Easy on the nutes ...no more than 1/2 label rate, for a couple weeks. Add a 2" layer of mulch/compost if it's gunna get hot, and you might wanna spray for bugs before flowers start to happen !! Acclimate them to handle 8 hours of direct sunilght minimum, if possible !  Don't wait if you live in the northern hemisphere !Happy growin
