I would probably leave well enough alone when it comes to fertilising unless
it looks like it's struggling a little otherwise you may kill it.
The pineapple tops probably won't go on to live into a full blown plant, I
remember doing it with carrot tops at school, however your vine has lasted
this long it should go on with no troubles.
I wouldn't worry about any hydroponic fertilisers either. I know you didn't
mention them but someone may as that is the way it's growing,
hydroponically. Most hydro nutrients can alter the pH, however one, Optimum
grow, doesn't, but you can still get a salt buildup in the plant and may
kill it.
You could try the smallest amount of Miracle grow/Aquasol etc. If you did
I'd mix it at suggessted rate, then add some to the water. e.g if your plant
is in about a litre, only add a tenth of diluted miracle grow, say 100ml.
The vine is probably getting enough nutrients from the water. It is
possible, think of fishtank plants. They may be meant for the water, but
would probably grow in wet areas of soil. Your vine may be opposite, it may
be meant to grow in moist soil areas, but will handle water.
Interesting topic though.
I know when I was about 10yr old I cut off a piece of diosma (I know this as
the plants still at my parents place) put in a small skinny twisted looking
vase, and gave it to my mum. The cutting grew roots, and when it got enough
I decided to plant in.

Yeah it does sound easy huh? Just leave it and enjoy it is my recomendation
