Strange Fluorescent Green Stain on Leaves

Hello fellow growers,

Ive been growing for quite a few years now but ive never seen this before.
The strain that has this issue is Alaskan Purple and its growing in optimal conditions.
Im also growing Skunk #1 and White Widow with the same conditions and they have no issues.

Please see the attached pictures and let me know if youve ever seen this before and know what it is.
Personally I think it must be a genetic defect. But Im looking forward to know what you think.

Thanks in advance.

im thinking its ph fluctuation and climate fluctuations.

pH and Temps are optimal. 27o lights on 18o lights out. pH is 6.6

Get your night temp up to 75f imo just because temp changes are huge. And when your lights shut off your humidity goes up and temp goes down. Which can be a start to many problems. I would be very surprised if that is tmv. Some strains genetics just also do that to so who knows.

Glad to inform that, whatever that was, didn't affect the grow at all.
