For the past many flushes ive done ive been having issues with water uptake. The majority of plants (not all...but most) stop taking up water ENTIRELY after the first flush. Ive done nothing different: Ph is on mark Water is good temp Its tap water that has been out for 36 hours And it gets oxygenated for approx 8 hours prior. They literally take nothing in. After a week i flush again for sakes say then again three four days later. In the past id have them dried right out four days later at max. Any ideas?
