Still not sure of what i am DOING!!!

First Question is i think i am getting close to harvest time i am at 50 days of flower on what is suppose to be purple urkle i have had some mite problems but not bad tricones are clear should i flush and only water from here on out should i continue using my humbolt Honey with the water or cut out everything I am growing Juciy fruit also any idea on flower periods of both ????

You can reasonably expect them to be done in 65-70 days. Flush for the last 10 days or so. I think a longer flush robs you of some yield. Most strains seem to put on a lot of weight the last 2 weeks.
Of course, that's just my opinion. Ask a hundred growers this question and you'll probably get a hundred different answers.
I think you'll be pretty safe with the above parameters though.
