Day 53 of flower. Day 68 of 12/12. Day 114 from seed.
I have to admit, this is taking much longer than I planned for this grow. Seems like progress is very slow, but everything looks fine.

Pineapple Chunk - flipped this one...
I am NOT an expert! My pH is very stable after having your exact situation.
I use r/o water
I rinse my roots and hydroton in a clean water bath at res change ( I fill a bucket and let the plant rest there while I mix everything up )
I use beneficial bacteria too, and mix in some cal-mag
After...
I had exact same problem. I tried several "cures".
Someone said it might help to use reverse osmosis water, so I bought a system and the pH stabilized. Now it goes down VERY slowly and I rarely have to adjust.
After some research, I also found that the hydroton I am using may cause pH problems...
