Running rdwc 6 x 1000w lights 2hp chiller set to 65. Have ran the same system with same nutes before no probs but this is 1st time using tap water. Used tap through veg and had no issues. On wk 4 and since week 2 my ec has increased from 1.0 to 1.8 and ph from 5.8 to 4.2. I bring the ec back up to 5.8 every day and within a couple hours it starts to drop again. I have not added any nutes since the first time I filled up the system at half strength. System uses 180 GL. I top off with 30 GL tap water (let sit out for 24 hrs) everyday to refill the system. Again, no nutes since initial Filling of the system. Temps do get slightly above 100 due to 2hp chiller heat (my exhaust isn't big enough, too much space in basement- work in progress) but I don't see how that could be a problem with roots in the 60's. Leaves are yellowing. I know not to add nutes with current conditions but don't know why this is happening. I searched the web and found nothing. Any ideas?
