One thing I can tell you about the vals, including the jungle val, is that it likes to be crowded. A single plant seldom thrives on its own, but when closely planted with a lot more of its own kind, tends to grow rapidly and spread easily via runners that produce new shoots that start out at the base of the plant and travel through the gravel and eventually poke through. At the store we sold them in groups of 5 because there was a better chance they would thrive and spread in a customer's tank that way vs a single plant. I have never had any luck trying to grow a single val plant by itself, but when grouped with others of its species, it grew and spread pretty quick.
In regards to fertilizers... please remember that fish waste is a plant fertilizer. If you add too much in nutrients to a tank without enough plants to utilize them, you will end up with algae issues instead of good plant growth. If you are concerned about this plant needing more nutrients you might want to try Flourenette A tabs by Sera. You can target the specific plant this way by inserting the tab (or partial tab) into the gravel near its roots. I have seldom ever used ferts in any of my planted tanks, found no need... but the few times I have, these tabs worked very well. We also used them in the store show tanks where there weren't many fish and had amazing results there too.
thats so funny you said that b/c i was thinking the same thing that it didnt look like a corkscrew. the jungle one looks exactly like it. ok i will think about getting some more then. yea i never overfeed the fish so i know im not putting too many nutrients in the tank.. ill def look into the tabs
