Right now my leafs are turning yellow, I'm in week 3 of Latewoods Flower. The only different thing I have done is switched into their buckets. Before their were in a smaller tray in flood & drain system. Now there in buckets with sprayers that go on every 2 hours for 15 minutes. Do you think i'm over watering or not enough. maybe do i need to add calmag? I'm stumped, any help, thanks in advance.
