See why I hit it with PH down..
Could be low 7s.
Now I'm afraid to do shit ...
I want to drop 4 tsp of ph down per pool, but...
I'm chicken. .lol
ATP it could be PH swing in full effect. ..IDK. ...
Good news though.
New growth showing up all over the place. .
Why dont you let me send you my guardian PH meter, you figure that shit out in 2 seconds, and send it back cheap bastard ! haha
It is strange to me to see that you're running ph in the 7's when d9 and everyone else seems to be just fine with letting the ph swing normally through the recirculation cycle and multiple feedings, without adding a drop of ph up or down.
That being said, I recently just switched to jacks w/ calcnit + RO. After mixing my 1.2 ec solution, my ph sits at 4.3. Never rises. I HAVE to add ph up, when others dont. After I ph up to 5.5, my water then drifts to about 6.1 before I need to refill and remix nutes.
I am running DTW coco, not recirculating in turface, but one would think that because i mix my nutes like everyone else, my ph should be about perfect ( like everyone else)....
But its not. and thats why this shit is confusing.
My only advice; get a damn ph meter, and make sure your water is in the proper range. The ram-horning of some of those plants screams ph lockout issues to me. If your water were in the range (5.5 - 6.3) I dont know if you would be having such adverse affects throughout all of your plants.
I know you;re not rookie, so dont take my advice to boot. Just an opinion.
