I took your advice (and what I was honestly thinking today at work) and lowered my light 3 inches so its super close. I put my big fan on top of my bulb unit, and it does not get warm at all.
Checked pump today for "goo" wasnt aware of this gunk until a post today, only noticed salt like substance on top of the pump, fins clear of any substance. also turned up pump speed.
2nd sprout has roots coming out bottom now
first sprout had a root about a foot long now, no longer taking it out of its spot.
two flowering plants, both are leaning, I untied so they can bush more later
I may just dump the double branch plant and keep the single stem for later.
