I accidently fed with my Sensi Bloom A + B, Bud Candy, too early. Is it too late to switch back this next feeding and feed them some GROW nutes again to get them a little bit taller or will this be bad for the plant?
It's fine. Understand that nutes don't make a plant bloom, they just support blooming when it goes into the flowering stage. You could feed it bloom nutes the whole time and it would just grow slower due to lower nitrogen levels, but it won't cause the plant to bloom.
honestly most ''micro'' and ''bloom'' forumlas have N in them as well, i can complete a grow with just micro and just barley any bloom, its all marketing to get our money...FYI i use AN and my Micro forumla has MORE nitrogen then the actual GROW formula, funny eh?...so what the fuck am i using the grow formula for then??
