I am about day 45 of flowering some WW and 1 has started to change colors from white to orange. It is about 15% orange so I changed the reservoir to straight water ph 6.0

I am just wondering there are still lots of white pistils on the plant am I flushing too early?

I am going to wait till the others start to change colors too.

Im expecting them to be done march 28th Is 2-3 weeks in hydro too long to flush?

You are most certainly early for flushing. Flushing is usually done for 3-7 (or sometimes up to 10) days, at the very end.

You shouldn't be watching your pistils as an indication of readiness for harvest. You will want to find your harvest window based on the condition of the trichomes on the plant. Trichomes will start clear, then progress to cloudy, ending in amber. I have this picture, so I'll stop explaining what it already does (and better than I).
