It's the only plant that looks like this, although some of the other leaves have the light green margins like this one does, only more pronounced.

Leaf of another plant, no brown spots but margins are yellowing. Potassium deficiency/lockout? It's lower leaves only so not calcium.

Looks like Mg deficiency or lockout. What's the pH?
Thanks, don't know at this point. I've got a cheap tester somewhere, but as I usually mix up a super soil & go for it I don't bother much with pH unless something starts to look off.
 
Grab some nature's living soil concentrate and add about a cup to the top and water.
 
Are you feeding it anything? pics of the whole plant would help
