Harvest timing?

This is my third real grow using FF Ocean forest and trio nutes. 1x Elev8 Gorilla Glue #4 and 2x Ethos 10th Planet. Currently day 66 of flower. Watering every 2 or 3 days, alternating with feeding or straight RO water ph 6-7.

I need to harvest all the plants at the same time, and I’m thinking I’m in the window for 2 of the plants. Maybe give it another week for the last plant to catch up.

I really appreciate any advice or thoughts on my plants as I get closer to the finish line.

They look very nice, excellent job. I think your plan of waiting a week then harvesting is a good one.
