Here are the pics of my himalaya gold, its growing outside and has just started to flower. Some lower leafs have these brown dots on them, some have just a few of them, others are completely burned, as you see on one picutre. After looking around i found out that this is probably from pottasium defficiency, but i think i gave it enough nutes (maybe too much), so this must be a pH problem, resulting in a lock-up of nutes.
My question is this- is this really a pH problem, in which way do the nutes tip the pH scale (does the soil become more acidic or basic) and how to solve the problem, prefferably without commercial pH uppers and downers. (in short, would throwing some ashes around the plant help...)
Thanks for any help.
