I talked to some guys that have been installing this for years and they did have a problem when using water soluable fert. It was building up residue and wrecking diaphrams in valves. They said it took a few years but it did happen. When they switched to liquid it solved the problem. Everyone I have talked to loves Mega Green 2-2-2.
