yellowing leaves....

ok I have a plant that is having some yellowing leaves. Story goes that I have this plant she is about 7 weeks into flowering now. I thought she was close harvesting as her trich's had become a solid milky white. As result I had started flushing her out, maybe one or two days only. Then the plant began to get new growth, So I began started her back on her reg feeding sched. Growtek bloom boost at 1/4 recommended strength, and growtek pro silicate. She gets the bloom boost with one watering than the prosilicate the other watering. My Ph is at 6.5 so no problems there as i'm growing in a soil medium. I have tried to give my plants a nitrogen supplement to aid in the yellowing at a very low level. The supplement comes in 6-0-0 and i mix 1/4 recommended dose. Keeps getting worse. I know its not the plant loosing its leaves due to harvest because my pistols are still milky white and not receded down into the buds and my trich are still a milky white. any ideas on what to do?

You should always try to include pics to aid in diagnosis. But, with everything you said ("7 weeks into flowering"... "her trich's had become a solid milky white") it sounds as if the plant may have been close to harvest. If so, you should not have fed plants.
