Hey beautiful plants, I do dwc and water has 0.4 EC and was having issues with EC rising and Doc Bugbee was running some ammonium nitrate with his grows so I supplemented with it like 10-15% and it leveled out the ph but that works for my setup. Only problem is ammonium nitrate doesn’t show up in the total EC so…? Just an idea to stop the yo-yo. When my EC goes up I think the plant are drinking more water than nutes I think. My Thai/Lao stuff is not hungry for nutes, run 1.2-1.4 but that being said could be higher since ammonium doesn’t show on my blue lab EC meter. Plants are so awesome genetics are coming out
