females need some help

The problem is on a couple of plants 2 plants are in the flower stage and one is about a month old. It starts out as small copper or gold spots and follows the veins in the leave. Any help would be appreciated.

flush your plants make sure you flush them to hell 4/5 times wet them through with water set a around 5.5ph.Then i would lower feed just 4 a couple of week then slowly increase the feed till you are on the same has before,don't give any feed at all till plants are just moist not far of dry.pull all the yellow leaves off your plant in the picture i can see loads i'm not saying has soon has you see a little yellow pull them off but once they are fully yellow they have done there job.get back to us and let us know what happens

Thanks, flushing worked. No new damage.
