So it's not really a problem so to speak, everythings under control and i'm not worried, just curious to identify why something happened. Had a clone in rockwool sitting in a heated prop, looking picture perfect, straight leaves, nice and strong and such, but needed to leave it a few days so filled up a DWC tub, ph'ed the water, and threw the rockwool into a pot to be moistened by the bubbles, everything as i normally do. Within 2 minutes of being in the DWC, the plant had kinda failed on itself, so i threw it back into the propogator. 2 hours later it looks like this. The right hand leaf shows it off best, they have curled up kinda like an orange peel. First time it's happened.
