You might be right. I just figured if it was nitrogen, it would’ve started with the lower leaves since nitrogen’s a mobile nutrient. It may have just been the fact that they’re only on their first sets of leaves that threw me off. I was thinking they’d be getting some nitrogen from the calmag foliar spray since it’s a 3-0-0, but it may be that the pH of the foliar spray was out of range for the nitrogen to be available (I had it above 6.2 pH as per the tutorial on coco for cannabis).
