The first time you mix a batch, PH after adding your concentrate and remember the amount of PH solution you added.
The next time you mix, add your PH solution to the RO first and then add the concentrated nutrients.
This reduces the chance of concentrates coming in contact and causing fallout.
If you need to add a little bit more afterwards, that's fine, but make sure the solution is being stirred when adding.
