browning around the edges of the leaves on top of the plant

I dont know what is causing this, from what i heard it could be the plant wanting more P, is this correct? It all on the new growth to, the plants goin into the 3rd weel of flowering

Help?

sounds like a mag def to me

how would i add some magnesium?

epsom salt, disolve a tblspoon per gallon in hot water

would i wanna keep doing this every watering?

i looked at photos of mag def, it doesnt really look like it, but would it still hurt to put some epsom salt in it?

on the edges of the plants its a dark brown on the leaves and then the rest of the part of the leaves look healthy.

It's possible that it's just nutrient burn (too much nutrients). Does it look like this?

what would u say this is from?
