Moved the rockwool into my DWC buckets, one is 5 gal and the other is slightly smaller I believe 3 gal had roots popping into the water on daycan3 in the buckets, I had my fan to close to my plant and developed a little wind burn on a leaf tip, also found white powder that was not WPM I believe it is salt from the water in my area as I was able to wipe it off, still treated with milk spray.
