So, my ppm/ec has doubled in run off. Generall 430 ppm (50% conversion) going in and 815 going out. I’ve decided to change my watering from one time to two times. My question is, can anybody tell me if it is alright to water right when the lights come on (which I have been doing), 12hours later and then once more, right before I turn my lights off? Meaning is it right to water then turn off the lights? Sorry as I am having a difficult one articulating this question.
