you should stop feeding 'Grow' type nutes (nitrogen) a week before going into flower cycle .... I use Earth Juice 'Grow', 'Microblast', and 'Catalyst' in vegging, stop a week before flower, then switch to Earth Juice 'Bloom', 'Catalyst', and 'Microblast' ... I also use a drop or two of Superthrive in the veg stage, as it helps rooting (and thats all it helps, folks, don't believe everything you hear ) ... I stop all feeding 2 weeks before harvest, then only water, and stop light and water the last 3-4 days before harvest ... :smokin:
