the only other pot i have is about a gallon and a half bigger, is it really worth the stress? also what can happen if i leave it in the pot its in? also about the molassers and epson salt will ordinary molasses work and how much of each should i use while watering?
You won't stress the plant if you repot carefully. Your plant will be much better off.
You can use grocery store molasses, just make sure it is unsulfered. Put a teaspoon or so in 1/2 to 1 gal. of water, I forget the recommended dosage, but this is about what I use. Epsom salts is magnesium, you might want to read the sticky posts on plant nutrition before you use it. Remember, less is more. I just put a small amount in my molasses water concoction, about a 1/2 tsp. I also use seaweed and disolve a couple of alfalfa pills in my mix. My plants love this stuff, and I use very little fertilizer, with good results.
Of course, some strains of mj demand more intensive feeding...but that is another kettle of fish. Your plant is begging you to hold off the nutes.
edit: Molasses feeds the soil by stimulating microbes which help the plant take up what it needs, promotes chelation, etc. But you can use other sugar syrups to do basically the same. Molasses is best though.
If you are using tap water, make sure you let it sit for a a day to let the chlorine evaporate. Water with just water at least every other time.
