F26 in the aeroponics 3x3

I’ve been more diligent this grow keeping the reservoir within tolerances, last grow I just YOLOd what was in the reservoir as long as the ph was in check, the ppm was off the charts. Plants didn’t seem to mind it too much though, so I never dealt with it.

This one, last week I vacuumed out as much of the reservoir as I could and refilled it new nutrients as it was 4.5ec.

Today PH was 7.1 and it was 3.2EC, so I added some tap water with some PH down and will check it later today to see where it settled.
