When to harvest lambs bread photo?

Hello wonderful people I could use you all’s wisdom. I am currently on my 2nd grow and first time using the scrog method. I beat the hell out of the plant using the net and at night the temps drop which the plant does not like however it still managed to produce sum buds. The plant sprouted first about 15 weeks ago which I kept it in veg a lil longer than I prob needed to but based on the pic how long do you all think until I should chop her?
Edit** Also I am using 50 50 Coco perlite


Looks like youve got about 2-3 weeks left


Agree, at least 3 weeks to go.


Will do appreciate the feedback
