Bump, i think it might be a magnesium deficiency but i'm not a expert so, anyone got some opinions?

The middle and upper leafs crawl upwards, are very dry at the ends and they leaf got cobber colored spots. The lower leaf seems least affected, they got some spots of cobber colored marks but that's it.

I might also be using to much food and having a nute burn. : /
