It looks to me like it got some damage, perhaps in transport? and it's just forming scars. Browning at the tips could be due to chemicals in tap water, you could try distilled water, it wouldn't bring the browned ones back, but could avoid further browning. Beautiful plant!

Thank you for your thoughts, Leslie! I see how that could be a potential cause. I did not think of it at first because I've had the plant for quite some time and now is when the marks are really appearing.

As for the tap water issue, that's pretty surprising since I live in NYC, which is usually praised for its tap water! I will consider getting distilled water (perhaps gallons?) from now on in addition to the fish emulsion I am buying for added nutrients.

If I had to water all my plants with distilled water, I'd go broke. I have always used tap water to water. Last year I bought one of those Brita water pitchers with the filter and now I'm using that but I haven't really noticed a difference. I agree with LeslieM that most of those marks look like they were caused by transport/mechanical damage. The brown tip is minute. Overall the plant looks good. Wait until it puts out some new leaves then chop the ones you don't like.

Some plants seem to be more susceptible to tap water than others. I believe its mainly the fluoride that will brown their tips. I have generally just given my plants tap water, and if the brown tips get too unsightly I cut them off. I agree the brown tip in the photo is minute, and could be due to damage like the other ones seem to be. Pothos is a very hardy plant, mine get tap water and are fine. If that's the only brown tip I wouldn't bother with distilled water.

Understood! Thank you both so much for your feedback. It was super helpful.
