Get rid of the foil and turn the fans back on!

Foil is not good to use. White paint is a lot better than foil, if you can't afford mylar ($2 at Walmart).

It's good that you have intake air now, but that is no substitute for interior air movement. MJ loves a breeze. Because of the way my grow area is set up, I sometimes have skinny-stemmed new clones right in front of a 12" oscillating fan. The plants will bend wayyy over when the fan passes - looks like a palm tree in a hurricane - then bounce back as it moves on and they do this all day long and pretty soon I have plants with very strong stems and I've never damaged one yet. Anyhoo - keep the air moving inside your grow area.

Good luck!
