Gold Speckles on leaves

I think the problem is just cal, but a bottle of cal/mg is a very easy answer,
I say this because I’ve seen this before, weather they where running RO or there where PH swings n starting to lack or lock out some stuff. Little cal/mg stopped the problem (I’m also assuming the OP checked for bugs) the fact that that problem is so even along the veins , makes me think it’s not bugs.

Same reason it cant be calcium..calcium is an immobile nutrient, problems won't appear half way down the plant first! Also, the specs wouldn't just be on the veins for a calcium deficiency. Not to mention, if calcium is lacking, the root zone becomes acidic fast and there would be a host of other problems showing! The reason cal/mag is so popular, is because people have issues with ph often times, and adding cal mag, can fix the ph issue over time, but its not the actual element of calcium or magnesium that's lacking..it's just that those 2 cations have the greatest attraction to the cec sites in your medium..so if the cec sites are occupied by say too much potassium or iron or aluminum if ph has gone too low, then calcium and magnesium can help re-populate those sites by knocking those ions off and replacing them, and in turn, correcting the ph over time. His issue though is not a ph issue as again, the whole plant would be affected.

You could be right ,
Let’s watch it play out .

It just doesn't look like mites to me, they leave more whitish marks plus every bite that I can see in that picture is on a vein and mites arent that perfect, still has op checked his plans yet with a magnifier? I agree, this is an interesting one!

I figured it out. The sugar maple tree that is in the vicinity of the plant, has begun its pollination production. Evidence on other leaves of different plants around and knowing this is the time of year they start. When the pawn say mixes with the do it makes it stain the leaf. An old local grower gave me this opinion and i am firmly believing

I don't think that a stain but just keep an eye on it, looks good otherwise
