Ok I've never done dwc with top feed first timer. Day ago around five am my lights went out. Theve been on 18/6 day after I fixed lights leaves are yellow and Browning. I have been using to water testing at 125ppm and was 7.1 ph but lowered to 5.69 ph I need some help I have already lost one earlier wasn't using any nutrients what is going wrong also room temp around 75-80 using cooled 600watt mh
a picture would really help, also did you say you are feeding at 125 ppm? you might have burned them from feeding them. you really don't have to start feeding them till you see the seed leaves start to yellow. also 7.1 is way to high, you wanna be 5.5 to 6.5. how many gallons of water do you have per plan? are you letting the water sit for a day or some to remove the chlorine? you want to check your ph a few times a day untill you know how your ph is gonna swing. you always want to keep an eye on your ph.
