Leaves turning spotty, is it PK deficiency?

Hi

Plant leaves having some spots, is it PK deficiency or something else??

Also you can see small buds versus big buds, posted before that one plant had this problem with small buds, most of hairs are brown already, I dont know what caused this slow growth. it is week 6 flowering and one plant is like a champion where the other one just not packing them buds



Thanks for your input

For me it looks like Manganese deficiency.

I had similar problems in veg and i think it was the pH. I see some canoeing of some leaves, maybe that can be an indication of what the problem is.

I wish I had a "calcium deficiency" shortcut button on my keyboard...

May be sodium toxicity but probably magnesium, I'm having the same thing happening to me an a lot of other people, but like dude said your ph is probably of locking out nuts.
