Is it ready for harvest?

Hi Sagar, sorry your grow didn't go as planned but I'm sure you would of learnt lots of lessons along the way. Looking at these photos it could require a little more time. I don't see a great deal of amber trichomes in any of the buds while zoomed in. I'd say its close but not quite ready. Best thing you can do is get a microscope and watch the trichomes, once majority of them are milky white and 10-30% have become amber that's when I would harvest this plant.

I would recommend to start flushing them for 10 days and have a eye on the teichomes (pic1 60%milky)if you have used some mineral fertiliser if you use organic fertiliser then wait until at least 20-30% of the trichomes starting to get brown. Pro's do not only look at the trichomes everyone know that there is a peak of terps you will smell it if you know when their at their peak this need a lots of grows for most people. And this is really hard most people harvest much to early, and the gap where the harvest is perfect is small after that the terps and potency will fall rapid down. So it is for most cases better to harvest them early then to late.
