What's happening to my leaves 3 days after 12/12 flip?!

[WeedMan2020]

So I flipped my plants over into flower 3 days ago and noticed today that I'm having a strange deficiency on one plant that I can't quite pinpoint whether it's a CalMag deficiency or something else.

In all seriousness though, I'm not sure. Will bump your thread though and see if someone else has a guess.

As a shot in the dark, maybe start of iron deficiency? Is it limited to just that one leaf? Anything else going on?

Just this leaf and one other one that's not as bad on a different branch. I was also doing a bit of research and came across 'Iron Deficiency' that looked quite similar and heard that the cause could be PH related, but my other plant that I'm growing alongside it is fine and I always make sure my PH is between 6.0 - 6.8, so it's making me question whether it could be some other issue..

I also changed the light to a HPS 400w from a CFL 300w that I had for the vegetative stage, not sure if this could be the cause though.

Either way I fed my plants just now with just tap water pH'd to 6.5 to see if it could possibly be Iron and the soil pH being off is what could've caused it. Not like a quick flush could harm anything.
