The comeback plants.... Am i ready to harvest??

Hi i have some pics of my bid buddah blue cheese plants and am looking for some specialist advice, basically i had alot of heat damage when i used a small heater in my grow tent and it nearly killed two of my plants, alot of the leaves died along with alot of the yield, but 3 out of 4 have made a comeback, i wanna know if im close to harvest, to understand the plants fully you should prob red my old post (with pics) which showed what happened back then https://www.rollitup.org/general-marijuana-growing/499338-first-time-grow-my-big.html

But here they are now 3 of them are good alot of the damage has been overcome but one plant has never really grown anymore and much of it is basically dead.

PLant 4 (the alien) im gunna cut my loses and chop this one down its deformed and not really sucking up and water its been flushed



PLant three




Plant two



Plant one

Plant 4 second pic looks terrible - definitely dispose of that thing.

The others seem to have bounced back nicely. I'd wait 3-4 weeks. Tons of new growth. Swellin' up.

Cheers man, 3-4 weeks?? Do you think I will see more growth in that time then?? My trichs are all going cloudy, when do u think best to start a flush??
