Shake, doesn't GH have calcium and magnesium already? The micro has calcium and Bloom has magnesium, according the the GH website. Looks like the plants just aren't getting enough of the good stuff though. A pH pen is a good idea.
GENERAL HYDROPONICS
polishpollack Reviewed by polishpollack on . Yellow and Brown Spots on Leaves (Trouble shooting form included) 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 Rating: 5
