ok... so i have hesi nutes for soil. its 5 bottles that you mix and match depending on what week of growth your in. scheduled ok my problem is, i fill up about 6 two liter bottles at a time inside my tub and i mix up my nutes in them. they sit for a week or 2 while i use the bottles to water my plants. lately i have been getting white flakes inside my 2 liter bottles. and lately i have noticed a slow down in growth. could be from lack of light due to new set up transition. or i'm thinking its because my nutes have white flakes in them some bottles get it. some bottles dont. all bottles have the same nutes in side them.
so the guy at the hydro shop said its most likely my vitamins i add . i have what is equal to super thrive, but its part of my hesi nute system. when i shake my 2 liter bottles i keep my nute water in, it looks like a snow globe (i grow in soil)
