Growing in coco, week 10 in flower i think. Started to rapidly decrease ppm few days ago as my plants are well in the harvest window. But today i found that 2 leaves started to turn purple. Should i feed more, harvest or continue with low ec water around 250 ppm?

I'd say that if your trics are mature enough for you to flush, then it's probably just the plant senescing(fading).
 
I typically feed until I have very few clear trics left, and then water only for about 10 days.
That when I'll see fading and trics get some more amber showing.
Then I chop.
