transplant or no?

right now my plants are in 2-2.5 gallon buckets, will that be alright or will my yeild be significantly reduced if i don't transplant into 5 gallon buckets?

plants grow according to the root sze, the more room to grow the larger your plants will be. Bigger pot=bigger POT

it would be jus fine but the 5gal might allow for more yeild. i always use 5gals
