all plants shed the oldest leaves ... by studying the plant.. you should be able to tell which are the oldest leaves ...

your plant is stressed ... most likely moving from grower [perhaps green house with perfect light and humidity.. etc ....] .. to the seller.. and then to you ... many cultural variables may have been impacted .... and would be stressors ....

there is also potential mechanical injury .. meaning ... they were roughly handled with all that traveling .... so perhaps leaves were damaged .. in some minor way .. and said damage is just now showing ..

i would water it properly .... remove the worse looking leaves ... and let it settle down ....

i would hope the grower .... grew them with sanitary protocol.. and because of said presumption... i would not leap to disease or insect problems shortly after sale ... but of course.. i dont know who you bought it from ...

also ... you dont mention where you are. . but the sun is in decline.. and the plant might be slowing down.. and it is not uncommon.. even for houseplants.. for the leaf shedding ...

all that said.. its stressed.. and imo.. fert is not a response to such.. just let it settle down ....

just for the heck of it. can we have a pic of the whole plant.. rather than just the closeups of the problems ....

Thanks for the advice, Ken. I live in zone 9 and I keep this guy next to a southern facing window that I keep open for most of the day. I let the soil dry out quite a bit before it's last watering, so I suspect that may have added to the list of stressors.

Here's the requested photo. It shares a planter with a pothos.

If the pot does not have a drain hole in the bottom, watering can be tricky. Dracaenas are sensitive to fluoride. Rain, distilled, or condensate from an A/C or dehumidifier would be sources of water without that.

By next to the window, do you mean next to it along the wall, or next to it by being right in front of it? If not right in front of the window, the leaves will lose their variegation and hang at a more droopy angle in the future.
