Hey just started my second grow a little bit ago. First one went well by the way. Smooth sailing through, no problems except some gnats. Yielded 60 grams of buds I am very satisfied with. Anyways. I started a few more and had them outside during day and inside at night first. Got them indoor permanently now. I admit I haven't been keeping as close of care as I did the first ones. I'm noticing what I think are mites though. One plant was pretty bad and I got rid of it. Just found a few on two more plants. What can I do to get rid of them? Would a foliage spray of water mixed with onions work?
