Started with amino acids, and added kelp and humic acid. If you haven't tried these three things you should. Mind you these first four that are moved out into the other room three of them are sprayed with STS to stop the production of ethylene so that they will produce pollen and then self-pollinate, I also added a fourth plant that wasn't sprayed to be a mother plant. It collects the pollen and will be fully seeded out.
