flushing at last week ?

my plants are getting to finish.i will harvest one of them in a week.
i use biobizz full range and i will begin flush from tomorrow.
should i use plain water or water + molasses ( 1 tsp/ a gal. ) for flushing at last week ?

Do not flush with molasses. Flush, then from there on out water with molasses.

i will give only plain water at last week and that is my flush technique .
Should i use plain water first and then water + molasses ?

I just use plain RO water when I flush... Hope that helps ya bro...

Use plain water. Some people add molasses in the last week.
