Hey guys. So Im in the final stretch with one of my plants. It started showing some defienciencies. in the last two weeks now it has decreased the nutes from 1.3 ec to 0.9 ec. I decided to flush because yesterday i noticed the rez at 4.7 ph and it was time for a rez change anyway. I flushed with 0 ppm RO water no ph up or down. To my surprise 2 hours later the ppm was 94 and the ph was back at 4.7. I decided to another flush with 0 ppm water and two ph pens confirm the same thing the water is at 114 ppm and ph 6.0. Any one know what could cause non PH’d RO water to go this acid this quick? Could it be the nutes stored in the huge roots?
