The difference between us BV... is that I've been figuring out what the plants need for years, then I use the calculator to see what that is... you have a preconcieved set of 'ideal' numbers in your head that you would like plants to prefer, but you've never grown a cannabis plant and have no practicle proof to back your math. As a non cannabis grower... why do you spend so much time here trying to get others to conduct your experiments on their plants?
