Thats 4 weeks!

Nice size considering lighting and being a noob. The only thing that is a concern to me is the yellow fan leaves. I am not an expert but what nutes were you using. Looks like a nitrogen defitcantcy. I know you are in flower and you need high phospherous. But you still need a little nitrogen for plant health.

Maybe someone who Knows this stuff can give you a better answer.

As for the 3 out of 4 plants male that sucks, I almost always get 50/50, to bad it couldn't have been the other way around.

Great work in progress twitch!!
