Need some really good advice

Ok so this aint my first rodeo but the first time I have had this happen I have my plants in three gallon pots that,i have used before but this time the roots seem to be coming out the sides and the bottoms of the pots with holes in them two of them are under a foot and the two others are about two feet. I have gdp, a plant I call alex unknown strain also big bang and a pipi strain is this bad I would really hate to have to repot if anyone could give me some good advice that would be great.
