Correct.Thanks. Wait, you don't change out your reservoir nutes until 5 days before harvest? One batch beginning to end?!
I mix the initial res and then use the regular replacement of nutrients as a pH down. Only r/o water for the base, always topping off the res daily with un-pH'd r/o. The link in my sig has a more in-depth explanation. The tech is over 20 years old and, imo, awesome.
Once transpiration slows, I don't add additional nutrients and as I've posted I'll actually dilute what's there if it's too hot. 5 days before harvest I pump it to a lawn or garden and replace with un-ph'd r/o.
