I like your set up... I had the foil set up for my first grow and still use it in my early veg chamber, I have that panda plastic black on one side white on the other, in my area now. I noticed you don't have nearly enough perlite in your soil and water maybe sitting in your soil, that may explain the droopy leaves (basically your overwatering your plants because your not getting enough drainage when you water) space out your waterings as far as possible once a week at the least. when you transfer make sure you put some perlite in the new mix. I definately think this will help but I'm no weed yoda..lol. more like a jedi in training..lol.
