Without seeing the rest of the plant to know where it is or if it's caused by something else, calcium deficiency.

So is it a calcium def or too much nutes?

Yours is a mag def. However, you're over feeding, so whether it's from lack of mag, or it being blocked... that depends on your nutes and feed schedule.

OK
I have just begun nutes and once a week at half strength I also use flora blend by GH and maxigro. I am thinking of introducing cal-mag soon .good idea?

You can foliar feed magnesium. A tablespoon of unscented epsom salts in a gallon of water. Tap is fine.

Alternate feeds between calmag and your other feed. Between the florablend and maxigro, you've got high K and low Mg.

That may be fine, but maxigro has a solid amount of sulfur in it... just a heads up.

It's not:
Nitrogen
Phosphorus
Potassium
Calcium
Nute Burn
Looks like an upper leaf that was to close to the light along with something else playing a roll. What that is IDK, VDP, a deficiency of something or a general deficiency needing a balanced feed.
I know! It's an LEDeficiency! Happens all the time if your using LED!!!
You need to switch to HPS and BOOM, problem solved.

Boron deficiency for crying out loud.
Next.

Hmmm!
Boron!
I'd bet even money it's not boron but you seem confident so I'll take 2 -1, my 5 USD to your 10 CAN.
Does @Big Perm know what it is or are we all guessing including the OP?
If he knows what it is. Did the grow take place in hydro or soil?
He's not going to have a boron Def in hydro IMHO unless he rigged it.
I'm assuming (educated guess) the leaf was plucked in veg so it's not very old.
He's a newbie in soil I think and constantly runs into issues.
It's probably not a PH issue and I would imagine there should be enough boron in the soil (I'm guessing this is one of his soil grows).
I'll stick with my original:

It absolutely can be Boron, and it very likely is, but Boron is responsible for Calcium uptake. They go hand in hand.
Without the entire plant pic, it can be Calcium or Boron. It depends on where that leaf is from. The OP said EASY, so I don't suspect it would be totally wild.

lol @Kushash
You nailed most of it. Top leaf, in veg.
% of plant with leaf issue: 1%
Coco/Perlite 60/40
ph 5.8-6.2
VPD: 1.1
I wanted the official answer. Was surprised at the answer I got. I showed Dyna-Gro. They checked it out and told me to raise my pH to 6.8
@hotrodharley where have YOU been man? Long time no talk.

General advice in soil. KISS!
Err on the side of allowing a deficiency by giving the plant water only versus feeding a variety of nutrients before the plant needs it.
As far as your plant a lot more info would be needed so I'd only be guessing and it's usually over fertilizing along with over watering and sometime not the best soil choice but I'd only be guessing. With the OP I had an idea it was his leaf and it was a game so I already have an idea of how he grows and what mistakes he is likely to make vs which ones he is not likely to make.

Some pics of the plant the leaf came from. I haven't defoliated since taking that one leaf off for the pic (defoliating soon, though)
