I had a feeling that might be the case. Which is a bit disappointing, as I can't make them get all their nutrients JUST from friendly plants, but I could fall back on food nonetheless.
There are other ways to get all nutrients from a single stimulus, such as setting an unused chemical to one of the 4 slots, then adding in a reaction which splits that chemical into two nutrients. That would just be one method, the great thing about genetics is you can solve problems in lots of different ways!
