Michelle, I'm sorry about your pothos that's supposed to have variegation, the person who sent it to you simply sent a plain green one instead of the variety Marble Queen. The variegation is either there or it isn't, has nothing to do with the amount of light, fertilization, etc. If you got it from a seller, offering Marble Queen and then sending the plain green species is dishonest and should be reported if that's possible.

Marble Queen is fairly common, are you in a state or country where it's rare?

Pothos will grow in water indefinitely, so no need to pot in soil unless you prefer it. If you leave it in water, add a few drops of liquid fertilizer every month or so during the summer.

Oh I didn't buy it online. A coworker was moving her pot around which had Marble Queen in it, but I guess also had plain green in it!

i might ask for a cutting of the marble queen then.

Okay Michelle, glad to be able to help you.
