Hey guys. its been a while since I posted in the forum, but I had a few follow-up questions for anyone who who do me the favor of answering them. I've managed to beat all of the other hurdles (rising ph, algae, aphids etc..) but I was wondering the best way to administer my nutes. I have come to the obvious conclusion that the way i'm doing it might not be the smartest. I premix the portions in a water bottle then add water to dilute so I can pour more over the hydroton to make sure it gets down into my res thouroughly. (While I'm sure FloraNova Bloom is a great nute, I bought a bottle and find the grit and clogs just unbearable..) Should I leave nutrients diluted in a bottle for such a long time? Should I mix then administer EACH time seperately? Also, I'm using the vinegar PH down method, and i was wondering how much can go into a res before the plant gets affected by all that vinegar... and is that even an issue?
