I have experimented with a few.... this stuff called sensa spray is supposed to increase the top nodes and decrease the space between each one when sprayed foliar upon starting 12/12, then again 7-10 days after. It burnt the shit out of a lot of leaves when I used it at half the recommended dilution. Big bud worked okay for a organic grow, and now I am using ginormous/big bud combo as directed with Humboldt Master A+B. This combo is a little pricey, but definitely not too much to hurt the budget, and the grow is surpassing anything I have had before. Anyone else have something to add? I am curious what supplements everyone uses during budding also.
