Curly leaves brown spots please help!

This is is my first grow so any help would be much appreciated. I transplanted the plants about 2 weeks ago. I started feeding them pure blend pro and camg+ both at the bottle recommended level. Since then they have got big fast but the leaves are kinda like taco shaped and I see these brown spot that look dead on the plants. It also looks like the new growth has holes in it. Any help would be appreciated. Also I'm growing in dakine coco coir lite under a 300 watt led light.

Also the temp is usually at 75 degrees and 50 percent humidity.

Cal-mag deficiency. Are you using ro water?

Ok thanks. I've just been using tap water.

What medium is she in?

dakine coco coir lite I think it a 70 30 mix with perlite

No such thing as a calmag deficiency

Phosphorus deficiency and it's from excess calcium almost certainly.

That should explain it.
