Yes. Maybe it is the perspective of the picture, but your plant looks about 2 - 2 1/2 feet high. If this is the case, you should be in about a 2 gallon container.
Second, that sure looks like MG soil, or something like it. If you upgrade your soil to Fox Farms when you replant, your plant will love you for it and you will pick up the trace elements which your plant needs in good organic soil. I recommend more perlite also. I use use at least 1/3.
