Discolored leaf. What is it?

[greentigerca]

Hey Guys,

I saw this leaf today on some newly transplanted DJ Short Blueberry (rockwool block into coco) and wondered what it was. I have had spots before but never exactly like this.

Thoughts??

Peace

How about a non-flash pic?

Hey GreenTiger, have you checked out the Sick plants thread in the infirmary. Basically sounds like you may have a Calcium Magnesium deficiency. Your pic is not too good because the leaf you shot looks too bright in the frame. You should consult the sick plants guide and see if you can self diagnose. I mention Cal mag issues because you also mentioned you had spots which is a calcium deficiency. Check it out:
