Looking for some help!
The first set of leaves started showing these black spots and started yellowing. I know these leaves usually fall off lately but i dont know what can cause this. I water thrm with rain water and only give them water when the soil starts to dry up. I use a 150W grow light at 50% for 12-13 hours.
The second picture is a little bit older pepper, it has some leaf deform and seem to stopped growing.
Can you guys give some advice what can be the problem?
