Whew! Was gone 7 days and all is well. My biggest concern was how much the pH would change. I left it at 5.3 and added several drops right before I left and it was 5.4 when I returned! I was expecting 6+ at least. The plants were growing right into the lights too so I raised them several inches. I'll try to post pics tonight.

Also, riddle me this...two of the plants are growing way faster/bigger than the rest and those two happen to be right in line with one of the sprayers. Is this coincidence(mixed bagseed, m/f) or can the little extra spray help them that much? See figure:

1 2 3 4
O O O
5 6 7 8

So the #'s=plants and O=sprayer......2 and 6 are the big ones. As you can see, the other two sprayers are slightly askew from the other plant sites, not right in the middle.
