I'm finding something odd with my pH levels. I cut the nutes in half a few days ago, to start weening them off. But since I did that, I can't get my pH to go down. I've added a pretty good amount of pH Down, but it continued to hover around 6.7. As a final solution, I brought my nutes back up, and the pH just levels off! I remember this happening before, when I did a flush. Don't know why, but I'll have to stay on top of my pH until harvest, even if it means giving them nutes until the end.
Anyone want to chime in here? I'm using GH MaxiBloom.
