I had problems with MG potting soil.
Nitrogen deficiency made the lower leaves yellow and I was using only RO water with no nutes.

Stinkyattic suggested an orchid formula which seems to have fixed the problem.

Next time, I won't use MG soil.
Just my newb experience. Thought I would share.
blink_inc Reviewed by blink_inc on . 2 weeks old, how do they look to you? 2 weeks old in a mix of miracle grow, perlite, and vermiculite. been watering every few days (when pots feel light (i have an empty pot to gauge :))) and misting the tops and bottoms of the leaves for the past few days daily. I noticed 1 or 2 leaves curling under at the tips. I doubt it is nute burn from just miracle grow, and the lights are a few inches up (and it is really like 2 leaves, not enough for it to be the light I think). This is all under 2 26w CFLs right now.
