I noticed that on some leaves (not the new ones) there were 2-3 yellowish spots. And on a large leave, a point that turns brown. I thought about a small deficiency in Magnesium?

It could be from early on. If its not got worse and hasn't effected other growth you may have already sorted it out. But over next few days if it gets worse you could have a slight calcium deficiency.

Hi mate, I think it looks like a calcium deficiency. Magnesium typically doesn't cause spots like that. Its more of a yellowing fade around the edges of the leaf. Hope this helps 🙂
