What should i be feeding there girls for there last few weeks

There almost 5 weeks into flowering On left is green crack feminised then AK Passion and white widow feminised autoflowering
I am feeding them potash fruit and bloom booster but I'm sure I can be helping them along a bit more

I personally do not stop feeding until they are finished, then I do a flash flush and let them drink water for 2-3 days.

I feed all the way until the last week and flush for a week and put into dark with no feed or water for 3 days. Chop and hang after...
