Not sure about pot size?

I started a random bagseed outside on may 24th, and its gotten about 5 feet tall, with 4 tops on it. I started it in a pot about two feet tall, and two feet in diameter (circle). Is the pot going to be big enough or should i try and find a bigger pot? Typically where i'm located, flowering starts early-mid August, and harvest is usuallly at the end of september.

gonna want a bigger pot. a 5 gallon buck with some holes drilled in the bottom would be able perfect for it but bigger is always better!

^ what he said

the bigger you want the plant, the bigger the bucket. It depends on the space you have.
