Great advice! You are of course correct. I actually just got off the phone with Dyna-Gro and they said while their stuff is not organic, it is much safer than other mbinorganics because of the lack of urea etc. Also, it contains all the elements needed where many plant foods do not. They said pretty much what you said on organic vs non.

They also, suggested I try going back to the tap water for a while anyway, because it may be that the RO is pulling out some needed minerals causing the tree to yellow. Also, they said don't forget organic foods need to be broken down vs inorganic.

Well, some of my trees I want to increase size but a few like a 40 year old Mikawa JBP, I have I don't want the shape to go wild. The Dyna-Gro I have is a 7-9-5, fairly balanced. I also have another product I have not tried yet that IS organic and is a 3-3-3. I think for now, the key is to get this yellowing problem under control. Who would think I would have to go back to tap water to possibly accomplish that!

Thanks...Any other tips greatly appreciated!
P.S. I think the Dyna-Gro stuff has .1% iron versus about .01% in my seaweed extract....
