To me this practice is a load of shit. I tried this with my last batch of beans. Non of them sank(not even after 1/2hour).NOTHING! So i dropped each bean in a cup of water. They all sank immediately.
hmm go to the local hard ware store and get a ph tester and flush your plant it shouldn't be needing more nutes then your giving it. im thinking lockout for sureThey are in mg organic choice. No nutes for 3 weeks of veg. When i switched to 12/12 i gave them ff open sesame 5-45-19 with a quarter teaspoon of mg 24-8-16 to a gallon of water for 2 weeks every other feeding. Then switched to ff beastie blooms 0-50-30 with a quarter teaspoon of mg 24-8-16 to a gallon. Just gave them their last dose of beastie blooms. One plant has been a total cunt for the last two weeks.
