Advanced cal mag makeing my res cloady???

Any Ideas. I have a recirc dwc with water chiller. 400w mh for grow and a 600hps for flower. Room temps are 18 min 27c max. Res temps are constant 18.5c. res is 80Litres. room is 1.2m x1.2m x2m..Total room Air exchange every thirty seconds. Res is out side the tent.. Nute are Hydromino... Water is R/O water.

This product i got the day before yesterday is making my res cloady takes 24 hours. PH REMAINS THE SAME 5.7. It's called Cal-mag Bloom by Advanced Floriculture 6-8-0-0. It is a yellow bottle with a picture of a tomato on the front. The only other additive i use is fulvic. Can't work it out.
I thought when your tank gos cloady it would smash my PH up. But nothing... Any ideas are welcome.
The plants showed signs of nute burn as well, so they have been on just plain water for half of yesterday and this morning. What do i do now?

here are the pics...........................

I think i worked it out,
The nutes that im using is hydromino, which is based around rain water not straight out tap water, so the nute has calcium aready in it. So it like giving the res a double dose of calcium. which i think is making it cloady. Any thoughts greatly appreciated.
