I'm mixing my nutes according to mfr. instructions. CaMg is also included in each feeding mix (before nutes). The solution is then pH balanced with pH-Down to around 5.4. Feeding can be anywhere from 2 to 6 litre per pot every 3 days in 3 gallon pots.
I am wondering about my runoff, however. When measured, the ppm is well within range of the inbound solution. My pH, is another question, starting high and never really coming down near the in reading, tending to stay in the 6.4 to 6.7 range. That is with 85% runoff in some cases.
Am I overthinking this and wasting nutes or do I have another issue? For completeness, ppm going in for week 1 of flowering was anywhere between 876 and 941. Copious quantities of nutes being used is from my attempt to knock the pH down flushing with my nute solution.
So it is known, the plants are robust and growing vigorously in this first week since switching lights to flower cycle. If there's an issue, they are being very quiet about it from all I can see.
