Is it ready?

This is my 3rd shot at growing so I know there's some faults but I just want to know if it's ready for harvest. Last I recorded, it was around 2 months 4 weeks old. Now it's probably into 4 possibly 5 months in. I was told to use a magnifying glass to check the trichomes, then the guy attempted to sell me a $25 magnifying glass and I left lol.

It looks like its revegging, what's your light schedule?
