Day 88-89 - PH still out of whack. Did a Res change, and still having the same PH problem. It drops hourly. PPMs now around 700.
I added 1/4tsp of SubCulture B with the res change this time.
Day 90 - 38F - Added a second air pump to Res. Both airstones were engulfed by roots, so i moved one into a more open area, and the second pump doubled the bubbles and the res is now moving much more.
Day 91 - 39F - PH was back to normal! (5.9). Hoping it was the lack of oxygen..
Day 92 - 40F - PH was still 5.9. Seems like everything is back to normal.
Day 94 - 42F - Changed Res/Nutes.
