I think I might try your tip Vox Humana, since I don't have a hose on my balcony, it would kind of be hard to try another method. I'll give this one a try. Do you think aphids are responsible for my plant looking poorly? Im trying to remember, i think i remember seeing the black things during the time my plant lost it's fullness. The plant is a bit sticky.

I'll let you know if it works. Thanks.
