hey all, i was wondering if anyone knew if it was bad to premix your fertilizer with water and let it sit for a few days. I am using bontanicare pure blend pro bloom and mixed it for my fertilizer schedule but realized i needed to do a flush so they sat there for a few days and today i opened up my gallon jugs and it had a sketchy smell. Sorta like that smella fter you come home from the beach like a sour sandy smell. I still watered my plants with them anyways. Do you think it was bad to do that? anyone have any advice/opinions?
