Gravity During Flush

So, during my flush I reduce all my nutes to molasses and Snow Storm until the last 2 days where the girls get straight up water.

I'm growing in soil, so I feed my gravity as advised on the bottle - 5ml/gallon, 2 consecutive feedings (sometimes 3), 3 weeks before harvest.

I was wondering if anyone has experimented with any other feedings of the gravity? I have really noticed exponential differences using this stuff...and I'm wondering what a light feeding for a few days at the beginning of the flush would do for them.

Thanks a lot. Even if you don't feed during the flush, post any experiments you may have tried with Gravity, and what gets you the best results. Thanks!

whats gravity? whats in it etc?

To be honest, I have no idea. I thought most people knew about it though...hmm.
