Harvest question

My girls are one Afgn Mango & P-xpress. I'm about to start my 7th week 2mrw. My calender says I need to give it 2 more weeks.

-When is a good time to just start feeding just water? I hear you do this so you dont taste the nutrients you've been using. I was thinking of week 8 just feeding straight water & no nutrients So then on Oct 25th I could stop feeding all 2gthr & let it dry out till Oct 28th. On the 28th harvest... What do you think?

I've always been told to flush 10-14 days before harvest. Newly found information suggests to me that flushing doesn't alter anything and a good dry/cure will get rid of the chlorophyll taste.
