Is my growth healthy?

Maybe a little crowded which could have some implications later. you only need 2-4 primary colas per sq ft to max out yield. This eliminates a lot of useless pruning and wasted growth/resources that comes with it. As long as the leaf surface fills the area, the yield will come one way or another. I like shooting for 2.5-3 colas per sq ft, but even at 2colas per sq ft i didn't really see the yield hurt.. Some risks with thicker colas, but too many colas increases portion of larft. There's a happy zone in the middle.
