Molly check the temps in you reservoir. This post is highly lacking the information we need to give a correct diagnosis but I would start with res temps. If your doing an
ebb and flow system this shouldnt be as big a problem as it would be with DWC but something to start with. I would be more than happy to help you diagnose the problem if you would like. I would love to see you growing better plants than Ron and will help you do so.
Ron: Why bother post if you have nothing to offer? Doesnt sound to me like your a big boy at all but rather an immature little high school kid growing plants under and incandescent light but.
Peace
