don't get that 1000 closer than a foot to the tops and at this point watch out for extremely fast upward growth that can happen so fast the plant will burn.

MG is a very touchy subject on this site. Personally I have had trouble with uniformity of nutrients in the mix. Flushing before using will help with that.

Six plants total, whoa, not much room to move in that. My state allows 15 and that is difficult to keep everything going right.
