"it was kept in relatively low light and I’ve never fertilized it. This are two things I plan to change. I’m also wondering if I should plant some extra cuttlings to make it fuller."

While not real sensitive to light levels, bright indirect light will certainly make a pothos happy. Mine is behind a triple layer paper shade and enjoys that.

You can certainly add in more cuttings if you want, or as it starts growing, twine the growing vines back into the mix and layer them (just dig in and put the vine into the soil, then put soil back over the top). Once it roots, cut the vine to set it free as a new plant, or just leave it in that curled loop if you prefer. I like the curled loops and the plant doesn't care.

Feeding is also a great idea occasionally. Pothos aren't heavy feeders and not particularly sensitive, but I'll just copy in my standard spiel about feeding. It's long because of some challenges. Sorry about that, but at least nobody can accuse anybody of being incomplete. We'll be going into the growing season shortly.

For feeding, MiracleGro or Dynagro. Lately, I'm turning more toward MiracleGro but will recommend either. The reason is that it actually lacks a few things that are in Dynagro. Yes, lacks. Most notably, calcium and magnesium, two elements that are in hard water and can (and do) cause tipping problems in many plants. Yes, there will be correct claims that chlorine and fluorine are the primary cause of tipping. That is true. Hard water is another cause.

Additionally, these (at 2% and 0.5% respectively) plus sulfur are not elements that should be added willy-nilly and are best added in a controlled fashion after a good, reliable pH test (which is another story; home pH tests are not good).

Dynagro also touts that it contains chlorine...something we set out our water to evaporate from it so it does not harm out plants, and which we openly acknolwedge causes tipping in far less than maintenance concentration (10 PPM if diluted 1 part per thousand, which most of us would far exceed).

The sodium levels in the feed are touted as a "nutrient." While a very rare few plants do use a tiny amount (https://www.tandfonline.com/doi/abs/10.1080/07352680390243495?journalCode=bpts20), excessive amounts are toxic. This is a bit excessive.

So yes, I actually prefer MiracleGro at this point.
