I seriously can't seen any porblems here...

do you have a specific question?

The heat will not be a big issue for you.. as long as you're not consistantly giving it a really high temperature (100+ isn't usually good)


Remember that most "plant problems" show up in the new growth as much if not more so than the rest of the plant...

Losing the bottom leaves is natural.. your plant will lose a good 40-50% of the fan leaves by the end of the plants life...it's just a way of shedding the unneeded and old material.

how long have you been in 12/12 2 .. 3 weeks?
