If your EC was 17 they would have been dead long ago! :-)
If it was actually 1.7 and you flushed them they're most likely hungry.
Give them an EC of 1.9 - 2.0 and they should be OK.

The yellow won't go away after feeding them. If the overall yellowing process doesn't advance too much more you're probably OK as during flowering it's not too unusual to see the lower fans start to yellow.
