I found spots on them and thats just what I did SPRAY! I found a good organic spray thats good up until the day of harvest so it says. So far its helped alot. I ran into a problem with my t5's. I placed them too close to the newborns and they didnt like very much. Most look as they will bounce back but two of them not so good. I plan on getting some more t5 lighting and some mylar so I can just grow in my closet. Was expecting to do an outdoor grow but my circumstances have changed so now its turned to an inside job.
