Afghani - The OG Indica

Looks like older leaves that had an excess of nitrogen. Plants look healthy from what i can see. They are low enough on the plant that you can prune them. In flower your plants wont need as much nitrogen. They will need more calcium,phosphorus and a small amount of magnesium. Best of luck on your grow.

Looks like it.

And it's a BOY so chop chop. Good luck 👍
