Nutrients Growth in feed jug

[Daxxor]

So when I mix a gallon of food for the girls, after a day or two I notice solid matter floating on top in the jug, Is this normal? I am using CalMag which I put in first, then my liquid seaweed, after about 5 min I do Adv Nuts Micro, Grow, Bloom in that order 5-10 mins apart, I add to a shot glass some molasses and mix in some warm water and break it up real good and then add that in, then I agitate it in the jug a few mins. I leave it set to room temp. before feeding the girls, i use about 1/3 of the gallon. my Ph is about 6.7 6.8 when it is done. My tap water is 7.0 and under 100 ppm.
