One single yellow leaf? Age thing or issue? Thanks!

First grow ofc and just noticed a single fan leaf has started turning yellow weirdly. Is this a age thing or is it the start of some issue, leaf is slightly below middle of plant.

It’s probably shaded and not producing so the plant is kicking it to the curb

So as long as it’s one and not multiple everything should be ok? And that makes sense

Yeah, everything else looks healthy
