Questions regarding flushing

I have seven lovely ladies, green crack, in coco fiber. They are are on their last week of flowering now, The trichs are just starting to turn amber. The plants are pretty small, one-two ounces expected from each. They have been fed the full fox farm nut cycle since I received them as little clones, using nothing but distilled water. The last feeding was Thursday October 29th. Pure water on Wed Nov 4th. On Sunday Nov 8th I watered them with more water than normal to flood out any remaining nutrients in the soil.
I don't think I can get another watering in before harvest (which seems to be four-five days away). Does this seem like enough time and effort to flush the soil?

better than nothing...if you can't water anymore before harvest, then you can't water anymore before harvest. You don't have much of an option. There are people here who don't flush at all, so you will be fine.

Yeah, I use hydro and I needed to flush for only four days twice a day hand watering them out of the tray....everything should be fine with your plants....i think the standard many people use is from 3-5 days....

you will do good
