Plant is Sick see pic's

[Baffled and confused]

1 out of 4 plants really looks sick. The others are showing some of the same symptoms but not as much as 1. Plants have been in flower cycle for approx. 9 days. have not shown sex yet.

Feeding cycle: 4 times for 5 minutes for 12 hour cycle
Fill and Drain system
Ph approx. 6.0 (using liquid drops test)
ppm 1540
cf 22
EC 2.2

Any help would be greatfully appreciated.
