ok, well too late. i bought a new one. but i still have the old bottle. i guess ill keep it around and use it when i run out. the guy at the hydro shop freaked out when i told him i pour the nutrients into a solo cup, then measure it out from there. Once i am done, if there is still some left in the solo cup, i simply pour it back into the nutrient bottle. He said this will cause mold and fungus to grow inside the nutrients. I find this hard to believe, and i never had a problem over my first 2 grows. What do you guys think? bs?
