DWC Purple Kush & The Purps

It's been 9 days since the girls have shown pistils, so I'm gonna say 9th day of flowering. Got my PPM's at 950, PH 5.6-5.9, RH 39% day and 49% night, res temp is 70 at its highest, but usually below. I added a dehumidifier and so far so good. Have had some brown slime on my roots, thinking not enough water movement, so I took 2 of 6 airstones out and left the hose in to agitate the water a little more. It already seems to knock off whatever it is on my precious roots. I'm steering clear of H202 because of my bennies and the fact that the plants are growing decent. Here's some pics

Pic 1 - The Purps (larger in size, more branching, was topped once, more prominent bud sights)
Pic 2 - The Purps
Pic 3 - Purple Kush (staying short and focusing more on the main cola, more potent smell)

Pic 5 - New 36x36x80 tent (needed the height with this light)
