My res is dropping fast and my PPMs are too - Anyone's thoughts?
Res changes are running 10 to 14 days apart.
My theory is / was, If the Res dropped and the PPMs stay the same, then the plants are drinking as much as they are eating - sort of my goal.
IF, the res dropped and the PPMs went up, then that was bad because they were drinking faster than they were absorbing nutrients. - Res mixed too strong?
Now I have res dropping fast, (10 - 12 days into 12/12) - BUT- My PPMs are dropping too.
This run of the res is now 8 days old.
Topping it off with a premixed solution could solve things, but then you would sort of be guessing as to what is missing.
If you just mixed new from scratch then you wouldn't be guessing. Res changes at this stage need to be more often than 10 to 14 days, they need to be at least every 7. Guess I sort of answered my own question there, again. Any GH hydro heads around whom I can stalk their threads out? Smoke another one!!!
