You say you're in 4th-week of veg, I suggest you give her at least 1 week (2 maybe?) so she can deal with any transplant-induced shock, if any.
I agree you can transplant. Some important advice. Do it in the shade. Do not shake soil of off roots as that will damage the roots. just place in new pot with the new mix around it. I always use superthrive when I transplant. For two to three waterings, I just add a couple of drops to the water. Then resume feed cycle. Also, the plant may seem to stop for a while, but be patient.
