I've started mixing my nutes 15 gallons at a time (in a 20-gallon trash can with lid and circulating pump). It's lasting about 5 days with 3 plants in full flower at 7 weeks old.
I noticed that the pH drifts upward so I have to add more "pH Lower" every day. Anybody else experience this? Anybody know why?
-Chlorinated tap water, 145ppm (comes from Lake Erie)
-General Hydroponics Flora series and CALiMAGic
-General Hydroponics pH lower (Phosphoric acid i think)
-target pH 5.9 (in coco/perlite)
-Gnome Moth Man (on the left) and 2 Mephisto Double Grape (100w LED for each)
