Need Help Please!!! w/ Pictures

Hi, I'm a first time outdoor grower and I need some help. The tip of the leaves of my plant are curling up and turning dry and brown. At first, I thought that it was because of heat stress so I gave it more shade to see if that was the case but it wasn't. I even checked the pH in the soil to see if that was the problem but it wasn't. I also need to know whether if my plant is ready to harvest because its been growing for a while now. I started in mid May and it started flowering around late June or mid July (I didn't keep a log book so I don't remember) Thanks for your help and I appreciate it.

harveast that now mann ...its begging to be harvested

Alright but should I flush out the nutrients before I harvest?

Yes flush it. Looks like ya have plenty to flush out.

properly flushing it takes 2 weeks ... when was the last time you fed it nutes ? The leaves are browning up because the plant is sucking the remaining nutes from itself .. If you did not give it any food within the last two weeks throw it in a closet for 48 hrs of darkness and cut her down

The last time I fed it nutes was about 3-4 days ago I was thinking about cutting it down in a week or so but i'm not so sure

flush it for a couple of days or more then put it in a dark room for 24-48 hours the chop done cure nd smoke..if u didnt add nutes it wud be the perfect time to harvest ..its just gunna take a couple extra days

alright thanks a lot man, I appreciate it
