I am growing in a 4x2x6 area with 2 shop lights and a 2 foot grow light from walmart. I just started on 12/12 3 days ago and there are brown/orange spots on a couple of the lower leaves. All the top leaves look fine. The closet is lined with the dull side of tin foil. There are also a couple brown/yellow edges on a few of the bottom leaves. I have been watering it around every 2 days. I haven't used any nutes either just tap water and miracle grow potting soil with moisture control.
