Jack Herer Seedling Lower Leaves Yellowing

What do you guys think of these leaves?

They seem too clumped together - I have feeling they should be more spaced out.
And curved down?

Also a dark edge around outer surface of leaves - possible calcium deficiency?
Mostly on older leaves.

I sprinkled some lime on the soil, so during watering more calcium will hopefully be added.

To counteract slight alkalinity of lime, I water with a slightly acidic mix, by adding a small amount of vinegar to the water.

It has grown since the last post, but leaves still have that dark perimeter. Anyone know when this will disappear, assuming it is calcium deficiency?

@granulat Those leaves won’t ever recover.

You think they are at least consumable?
