Veterans,
I posted a thread under the "hydroponics" section this afternoon about yellow and brown spots on my leaves. I was wondering if some of the veterans could take a look and let me know what they think my issue could be. I made the mistake of posting over their in that forum. Someone was nice enough to respond but by the time I got back to answer their questions they were gone. They thought I might be possibly starving them is that what you guys think? Any help would be greatly appreciated.
