When to flush gorilla glue auto fem

First time grow, 2x4 tent, 2 vivosun 300watt led, coco, fox farm trio, 3 gal fabric pots. 41 days from sprouted. Flowering. I have doing half of recommend fox farm fertilizer and some cal-mag. When do I flush?

FF has a feed/flush schedule… I go close to it, but like you, rarely go full strength. I went with the flush full strength, though. I’m not using any of the stuff in the middle, just the liquid trio and the powdered trio for flower. I use FF everything, so I stick kinda by this…
