Please help first grow with RDWC
This is my first time growing in DWC and unaware at the time my water temps went through the roof. Highest recorded was 28 degrees C. Pythium then went out of control and was advised by my local shop to treat with pythoff and then treat with peroxide. My plants went from healthy looking with preflower to stressed as. I keep adding acid as for an unknown reason my PH keeps rising out of control all the way up to 7.8 hours after I corrected the water down to 6.3. Has anybody experienced anything like this.
