I have these rust colored spots on one of my plants, I'm using organic soil cut with perilite, not sure ph still waiting for my meter to come in, and growing using led lights. I watered with Epsom salts thinking it might be mag deficiency but I'm sot sure. Any suggestions?

could be a ph issue...or a calmag def....i always get calmag deficiency using led lighting....could be burns from the light too if water was on the plant...
 
There's no such thing as a "calmag" deficiency.You have what appears to be a calcium deficiency. But it's hard to say since you've told us next to nothing about your grow... Key points like what medium you are growing in... What if anything you are feeding with... What are your watering schedules..are you using tap water? Etc, etc.

Ph could be a factor here.. Or it could be meaningless, depending on the answers to these very important questions.

Sorry I'm using just regular organic soil from Lowes, no nutes yet haven't fed any, I'm using bottled water to water them with. I water them maybe once a week.
