galz look sick

hi i need some ones expertise on the leaf problem im having dont know if its mag deficiency or not never had this problem before the leaf pic look like rust spots please help a grower in need

Yo you growing in 100% perlite?
How many ppms you feeding?
Is yo ph in check?
Posssible under feeding of ppms?

lol im not growing in perlite im using soil it was to keep gnats off had a problem with them f..kers ph is 6.8 but thats ok for soil

Looks like the start of some burn, what nutrients are you giving them, possible over feeding but I may be wrong.

im feeding with ionic right now thanks for your reply calimack

I agree with calimack, sliiiiiiiight overfeeding. What do you mean they look sick? They look as healthy as a silver metalist sprinter...could be a bit better, but in pretty damn good shape

i should of put some more pics up i have discolour in edges of the leafs its just seems to be only 4 of my plants that has this problem
