The lower leaves on my basil are turning yellow - almost white, actually - and going brown on the edges. Eventually, they drop off. I converted this basil plant from potting soil about a month and a half ago. I kept it out of direct sunlight, with a clear bag over it, with no fertilizer for about 3 and a half weeks. It lost a bunch of its lower leaves in the process and then stabilized. Now that I've moved it outside, it's going yellow again. It also doesn't seem to be growing.
I can't figure out if I should stop giving it fertilizer or start giving it more. I've only been giving it 1/4 - 1/2 strength hydroponic nutrient solution.
