Yellowing / Browning leaves

[MSchep]

Just wanting to get some input from this amazing community on what I might be dealing with here. These are a few leaves on my two Orange Oxheart plants, growing like crazy in an Earthtainer. I had all new mix this year, so I don't think this would be anything soil borne. Aside from a few of the leaves looking like this, the rest of the plants are doing great. Already almost 6ft tall, and probably 2-3 dozen fruit developing quickly.

I'm sure this is something common, but I just haven't experienced it yet, so can't ID it yet. Two pics of the same leaf, front and back.

Thanks in advance for the guidance!!

I'm no expert, but my guess would be sun scorching...? If the rest of the plant looks healthy and growing well, I wouldn't be too concerned at this point.

Thanks, and that is certainly what my hope was, that just isn't something i'm used to seeing, as the conditions around here are usually pretty optimal for the plants. This is happening mostly at the top, where there is the most sun exposure, so that would make sense. I'm still concerned, and will be keeping a close eye for other symptoms and report back if I see any.

Thanks
