Getting ready to flush, recommendations?

Soil, indoor grower getting ready to flush WW plants. About 2 weeks out to harvest. Currently using General Hydro nutes. 1200 PPM, (0-10-20) Bloom + Flora series.

I have heard people add enhansers to make flavor better such as a tablespoon of lemon juice/gallon flush. Anything work for anyone else? I also heard that flush you buy from the Hydro store is mainly sugar water.

Just wanted to get some advise from you fine folks, let me know!

i use molasses during the last few weeks....i used it my last harvest and it was the stickiest by far...tasted like a fresh grapefruit.
