:confused:Sounds like coco is inert , 200 is a Lil low dontcha think? Plants look great though? Must be using a dop3 foliar?
What PH Did You put in?Yeah so I checked my flower runoff and it was +150, pH 6.5. So I ran some ~200 ppm solution through them to give em a little flush.
6.0. And my tests are actually going pretty well. pH hasn't changed a bit since I pulled my airstones. I've got 4 different little tests samples going and as of 12 hours, they haven't moved. But time will tellWhat PH Did You put in?

If the air still bothers your ph try spraying the lid and you can switch from air pump to water pump to create a water fall in res which will aerate also but that could mess with your water temp...I didn't catch your water temp, but temp definitely messes with ph6.0.

Try this- instead of air stones(which will raise it), drop a little submersible pump in there to keep it stirred. Put it on a timer, doesn't need to stay on.
Personally I don't think res needs extra stirring, but... That's an old debate.
Also- try a batch without silica. That could be your culprit.
And one more thing, unrelated to your inquiry but still related- instead of one feed a day, try 2-3 shorter feeds a day. (You'll also want to reduce your ppms with more feedings, 600-900ppm give or take depending on system, plant size, nutes, etc).
Think of like this- when your trying to get in shape, or body building- do you want one big meal a day or multiple smaller meals a day?
The multiple meals increase your metabolism.
