Foxfarm bembe and cha ching?

[gemini_ranger]

I'm going into week ten with my lsd autoflower. Just picked up the three with cha ching and bembe.. had anyone ever used it? Do I just add it with the trio or feeding days? Or do I add these on separate days? Is bembe necessary? Because it said make fruit sweeter. Not really any fruits here.. any pros in the fox farm line have any tips? Because I'm thinking about getting the rest of the products to go fully by schedule for my next grow. I have what I need to go by schedule now. I.e. bembe, chaching and the trio.
