Acidic MSU-RO Solution Precipitates

[jmrathbun]

Following recommendations from this forum, I recently mixed a pound of MSU-RO fertilizer with a gallon of RO water (pH 6.8) and got a very intensely green solution with a pH of 3.5 and about 5 mm of whitish precipitate that sinks to the bottom and will not go into solution. Is this normal? I'm concerned that whatever is not in solution might be an essential nutrient, or harmful to my plants when I get close to the bottom of the jug. If I neutralize this solution, will that make things better or worse? It sinks so fast that agitating the bottle before pouring won't solve the problem.
