its day 20 My plant looks healty but i saw sonething like that on 2 leaves. What is that? And im pretty sure yesterday it was only 1 leaf. Second and third picture you can see the green points. İ dont know how to name it.
Grow Weed Easy - Learn How to Grow Cannabis Has a symptom page to match pics to. For a second I thought leaf borers but not enough damage to make that call.
I wouldn't without worsening. Spray with Neem oil. Monitor situation. If those were on backside of leaf I would guess bugs.
