First ever grow; Autoflowers; Organic

Hi GD friends It's been, a longggg couple weeks. Lost 1 plant to spider mites, none of the others seem to have gotten them though. Our Kush 2.0 white lights stopped working, its under warranty still and are supposed to be getting our new one today actually. We didn't want our grow to die so have been getting by with our Kale light. The leafs are VERY yellow, and a lot of them have purple stems. We have been a little worried because the leafs are yellow, then flush out to almost white. I feel like the buds are looking good, and the plant isnt droopy etc. Have been researching fustarium wilt Also our grow bags seem to have mold growing on the outsides of the bags? It's our first grow thou so if anything making sure we seize this as a learning experience. Thanks for stopping by. Any comments or opinions on how you guys think it's looking is MUCH appreciated!
