How do I fix the nutrient dispenser?

Hint 1 of 9:

Have Spock see if he can fix it.

Hint 2 of 9:

Nope, there's nothing Spock can do for you.  It looks like you're going to
have to find an alternate source of nutrients for the plant.

Hint 3 of 9:

Moll will tell you what nutrients the plants need, if you don't know a lot
about plants.  Just keep talking to her until she gives you the information
you need.

Hint 4 of 9:

Have you seen anything else with similar components?

Hint 5 of 9:

The blocks Jakesey is playing with will work.  See another question if you
need help in getting them from him.

Hint 6 of 9:

All you need to do is dissolve them into the solution that's already in the
keg.
