What type of light are you using? If you are using an HID light, did you just recently change to that from something weaker? They seem very stretched, a condition I am familiar with. It does look like you topped them or pruned them or did something to make those bottom shoots so thick and strong. At first glance, it looks like they are just majorly stressed from early on.

There is really not much you can do now, except for LSTing them and trying to train them to grow more horizontal. You could even lay them on their sides and let the shoots grow up. That would create a shorter plant. Other than that, I'd say, take clones and make sure they don't stretch that much next time.

They do look healthy, tho. Becareful flowering those, they'll grow so tall they will have to be supported for sure...and at that point, your light most likely would not reach the bottom shoots and leaves and they would die off.

Be cool.
