Yellow spots along veins?

Medium: Pro-Mix HP
PH: 6.0
I don't care about this plant because it's small, but I would still like to know what this is. The leaves were fairly dark/burnt tips, so I flushed it. My last post I was told it's probably salt build-up (on different plant), because I didn't have run-off water, it's on the top leaves & the yellowing isn't starting from the outer edge. This plant however always had run-off water & right after I flushed this happened, just like on my other plant after the slight flush. These pictures are from the very top fan leaves. Thanks in advance :)

Have you tried mag? That is strange. Never seen anything like it.

Not yet, heard you shouldn't need Cal-Mag in this medium if I use tap water. Hope that's not it but I suppose it's only 1 extra nutrient bottle to buy. Also, the only other thing I saw like this on google was on the 420magazine website. Wasn't quite the same though, but they never seen it either lol. They said it was probably just a genetic thing. The yellowing was more directly along the veins though & besides, this only just started so mine is definitely not genetics. Thanks again both of you :)

the red stem is magnesium deficiency, the yellow spots are too. You definitely need cal-mag unless you have hard tap water. You can also use epsom salts if you don't want to buy the bottle of calmag, although its really cheap.

Too much N ("The leaves were fairly dark/burnt tips"), can lock out Ca...

Why the flush? What are you feeding and how often?
