My white widow auto is at day 67 from germination. I can’t get the PH to hold in my DWC setup. I did have a problem with nitrogen toxicity. Flushed her for 2 days and cut back on the PPM by cutting back first on the GH micro and now I cut back on the bloom. But checking it again today the PH continues to dive from 6.1 to 5.1. (That was just today). It’s been a constant battle these past few weeks to get the PH to hold. Constantly change the res because the PH falls to dangerous levels. She was doing fine in veg and early bloom.
I’ve searched for root rot and have not found any. Been using hydro guard since day one. I just can’t figure this out and I’m worried I’m going to lose her when she is getting close. Please help with any ideas. Readings below:
PPM average during transition was 585
PPM since I’ve been cutting back is 201
Water temp has been averaging 77F
Average tent Temp 76.6F
Humidity averaging 47.8F
GH Nutes, cut back to 1/4 Tsp per gal for Micro; 1 tsp per gal for bloom
