Ok, so I'm writing this a couple weeks into my grow. It's gone pretty well but there are a couple of things that I would like to resolve. Some of my leaves are curling, while some are yellowing and browning. I would like to make this plant as healthy as possible but I lack the knowledge since this is my first grow. Any help would be much appreciated. Ive got a 20 watt cfl and am using organic soil that contains .10% nitrogen, .05% phosphate and .05% potash. If there's any other info I should give let me know.
