After a week of adjusting pH and ppms in my rez it occurred to me to convert to D2W. Easy to do, just reroute the drain tube to an empty container
during flower, and especially during heavy flower the plants dump high pH waste. Better to not have it recirculate, even if pH adjusted
And since I am feeding only 3xs during lights on, with each feed/spray < 16ozs, it's easy to replenish from premixed nutes
I'm excited to see what the next week brings
Also reduced ppms to ~ 340 as plants look like they may be 10-15 days from harvest
