I need some good advice on flowering

So, i'm not a beginner, i'm also no master. I been growing for almost 15 years. I do well in clone and veg, but i struggle in flower. I can seem to get big fat tight consistent buds. I was talking to a guy that says he feeds every 3 days in flower, i only feed every 10 days or so. Should i be hitting them more in flower? I wanna hear what nutrients people are using and how often

You should get bat guano, specifically from Indonesia or Jamaica. It'll stop most nitrogen from slowing the growth to the buds and it'll help the phosphorus shoot up, tightening buds and upping yields.
