Hi all, this is my first indoor grow. all has been going really well. thought i had a simple calmag issue, but now i’m not so sure. they started as very tiny, almost perfectly round rust/gold spots on a few leaves but it’s not improving and some of the new growth is now showing. second plant showing a few spots today.
i am not seeing anything raised but looking through a loupe and cheap microscope and it’s not 100% easy to see
I have 2 blue dream photos in the same 2x4 tent
Start week 3 flower
Coco/perlite with Advanced Nutrients Coco Sensi Ph Perfect, feed every other day at 75%, though lately feeding 100% to fix calmag (the base nutes have calmag in them)
I took out the loupe and got some close ups and am now sufficiently freaked out.
the light is bouncing off my countertop and backlighting this leaf. the lighter green ring is not visible to the naked eye.
back of the leaf…
EDIT. well cr@p. i’m seeing the spots starting on the other one now as well.
