Tips of leaves turned brown and yellowing toward the stem...
The issue is most likely beneath the surface, so trimming won't solve anything. A lot of times when plants start to get yellow/brown closest to the soil, the issue is overwatering. Winter is ZZ plant's dormant season, so they need even less water now than during their growing season in the summer. Non-porous pots and insufficient light can also contribute to overwatering. I'd pull it out of the pot and check roots for any signs of rot as the first step.
If you don't find signs of root rot, another possibility is that it's something fungal. Fungal issues can cause a leaf's edges to turn yellow first, followed by brown (similar to the pattern on your ZZ's leaves). Repotting the plant in fresh soil and a sterilized pot is a good first step for both issues π

@stephonicle hi! Thanks for the input. I rarely water it and the soils is quite dry. So Iβd be shocked if it was root rot. The yellowing is occurring at the leaves furthest from the soil. Itβs only on new shoots. Older shoots are unaffected. The yellowing ones are crispy brown at the tips. Iβve never had a fungal problem so Iβll research that more. Could be it. Do you think it could be from too much light? Iβm nervous to repot in the winter. Most of the plant seems healthy and I donβt want to cause extra stress.
@FitMockoyster direct light burn will usually singe the edges. Winter sun is much weaker than summer sun, so unless it's under a grow light that's positioned too close to the leaves, that wouldn't be my first guess. The reason I thought it could be fungal is the leaves look exactly like my monstera when it had fungal issues. Two leaves started yellowing at the edges first, then started browning.
Indoor plants are in controlled environments, so they don't necessarily adhere to the same seasonal rules applied to outdoor plants. As far as repotting in the off season, I look at it this way: are the potential benefits greater than the potential risks? With my monstera, which I just repotted a few weeks ago, it might not have survived if I'd waited until spring.
