Hey BK, that's outstanding! I didn't know it could help plants recover from pH stress.Cali, I'm happy to report back that the House and Garden Reverse Osmosis pH Stabilizer was added to my gardening regime, and is making a big difference.
For the plants that were already in distress it ended up taking 2.5ml/gal to bring them around to the point where it looks like they'll now safely make it all the way through flowering.
For all the other plants to follow, it looks like 2ml/gal is the sweet spot for now, at least.
Thanks again, you saved the day, sir.
I've also found it useful for after the pH crashes, you can use 3.8ml/gal with plain water to top up your rez. Obviously this brings the EC down and the pH up.
One more thing you can try is a re-mineralization filter on the back end of your RO filter. I got this one on amazon and rigged it up with a couple John Guest quick connect fittings. Brings the water up to about 0.08 EC. Some black slime came out the other day, I think it's time to replace it.
