Hello my Friends , Just noticed these tan dots on about 2 leaves at top of tallest bud ,
never seen nor had these ever . Anybody have a idea what they are ? Light scald maybe ?

Thanks,,,,,,

Any possible way that you inadvertently dribbled a little nuted water on it?

Did the soil get extra dry? low humidity?

Either pH
Calcium (don’t think so, too high up the plant)
Low humidity causing increased transpiration and burning the leaf.

I experience the same in winter(Canada) rh is like 20-30%...very hard to maintain higher, so thank you for the info @Nutty sKunK .

This looks pretty close to what I'm currently dealing with on one of my plants.....I have pretty low RH as well. Last week was 30-35 in my grow area. Now it's down to 25-30.

Running high pressure aero. Plan to take clones from this plant. All my nutes were mixed from dry salts using hydrobuddy. 5.5pH w 1.4 EC. 2-1-1:
