Okay, I mix my nutes about every 3 days. GH flora micro/bloom with 50 ppm tap water. In the rez are two pumps, one for circulation, the other feeds a wand. Both are always on.
Sitting right beside it is my flowering res. Practically the same, except micro is usually a bit lower.
They are less than 6 inches apart. The flowering res ph stays perfect for 3 days, but the veg res drops hard, usually around 4.8 by day 3. (my last watering)
I bought a new res, gonna swap em out, but before I did I thought id ask if anyone had any clues what could be causing it?
Temps are 68-ish in the res, no plant matter etc ever gets in it. Kept in dark, yada yada. Im assuming its some kinda bacterial thing maybe?
