Is it time?

Hi! I am looking for some verification if you think it is time to harvest please.
I put them into a flush 3 days ago thinking it might be time to harvest in the next few days.
My first time growing and don't want to push them to over ripe.

Looking good. Still another round of swelling to come imo.

also as per bobby

flush yer toilet, not yer weed

Thanks @bk78 I'm growing in DWC and using GH Flora series so I was concerned about chemical taste as I've seen others post about.
I'm still a super noob, I know nothing from experience except what I've already gone through in a single 7/8ths of a grow.

So not to late for one last feed in your opinion? Btw they are 2 different strains.
