Is it time to transplant?

Hey, I'm currently growing 4 plants they are 10 weeks old clones and in 5 gallon pots I would be transplanting them into 10 gallon pots. From what I've online people seem to have different opinions on when to actually transplant. Wondering what anyone else thinks. Here's a pic of 2 of them.

Getting plants out of fabric pots to transplant sux!!! You'd be better off planting the old fabric pot in to the new one. Also, being you're in a fabric pot, you don't necessarily need to transplant as the plant wont be near as likely to get root-bound. IMO
