Is expensive stuff...2.2 lbs for 70 bux...ouch!
Can spray plants but I wont spray them in bud...because this stuff when mixed up is black...very black.
Mix up says 1 teaspoon per liter if watering plants. Well I have a pail sitting for many hours now and only put in 4 teaspoon to 5 gallon of water.. Pre mixed it in a bowl then added it...takes awhile to break down...once you get in in water though it breaks down better.
Put ph up by 3 points...knocked it down to 6.4 before bed and today its staying at that number.
I have a giant kush mint male ...gonna test it on that one to see what it does before I feed all the others....as I'm not keeping that male plant so good one to pick for a test imo.
