I moved my Orange Bud into the DWC bucket a week ago…
I used a rapid rooter, I top watered every day ( about 4 oz) with pH’d water to 5.5…
My water temp is steady at 69f…
My PPM is 565…
You have a start stop timer? Could have overwatered without one or the pump heated up your solution. I have seen start stop timers now for under 30.00.
