I now think I have a Cal Mag def and proaly iron since they all go hand in hand, And thanks to some fellow members, I thought this thread was dead I also have a post Neon green with rust spots, u can check it out. I started that one cause no-one was helping me in this thread. Let me know what you think, these are a little overwatered but that was yesterday, am going to feed them with cal mag plus and nutes.

Does anyone know the effect of adding cal mag with a tea (benificials) and also Ph. I think if I remember right, you don't want to adjust the ph when adding in Tea cause the ph down will kill the beni's. I am using RO water, Thanks in advance
