Had a problem with pale color on the leaves between the veins, but that was a low nutrient problem, fixed now (I think)
Here is what I am getting now:
Some have just this pin prickle spotty stuff happening all over.


Other leaves have this same strange pattern. They get the little spotts along the edge at each zig zag of the edge of the leaf.
Nothing dramatic to look at just one leaf like this, but when I start seeing this same pattern on different leaves in both plants
I have to wonder.

Used a 30x scope and can't see any pests on front or back of leaf, shake the bush, nothing flies out. I had been wondering could it be dust from my ceiling falling on the plant and killing the spots it lands on. Only I doubt bugs or dust too because the spots seems to be the same location - on the zig zag part of the leaf. Last plant did this too and I cant figure out what it is.
Thanks for any help.

the dirty looking leaf i'm not to sure on, but i can tell you the spots on the zig zags are almost certainly calcium deficiency, i deal with it a lot because my tap comes out at .05 ec (~30ish ppm if u use 1000ppm peak) i hate to say another webiste but there is a plant diagnosis thread at icmag that has pictures of a calcium deficiency and it looks just like it

search for calcium until you get to the pic of an early deficiency, hope this helps


ps- calcium is an immobile element, so you not be able to fix the old growth, but the new growth will not have spots if you fix it. in my hydro i add about .3 EC of cal/mag to the res before i even start
