Are these plants sexed already? If not the larger they get the more problems you may encounter later. Assuming you wait another 3-4 weeks till you flower, that's 3-4 more weeks of growth of the male roots (hopefully you don't have any, but odds are against you). 18 gallons is a really nice size for 4 plants, but in seperate containers, and assuming they are all female.
