First grow, should I harvest

First time grower, sorry for the amount of pics. Just wanted to give best possible photos I could. First picture is of all plants. Next 3 are a northern lights. Next 3 are green crack. Last 3 are a blue amnesia. And any guesses on what I can expect for harvest amount

If it makes any difference there all autos and has been 14 weeks since popping out of soil.

Chop away ...nice job !

Beautiful work! No amber seen in pics, I would let them run another 7-10 days myself.....................
