SaviiBuds Definitely have the beginning stages of a deficiency, do you see how the problem is showing up in-between the veins on the leaves? A good rule of thumb is if a problem is showing between the leaves it is a deficiency and if it is crossing the veins it’s more indicative of a fungal pathogen. I would guess nitrogen in this case just based on age, but could possibly be magnesium or zinc as well. To confirm it’s nitrogen, you could mix up a light nitrogen foliar spray and apply it. If that’s the issue, they should start to green back up pretty quickly. The other option would be some sort of lockout. Are you in soil or coco? What pH are you watering in at?

ashton420/7 I’m In coco and water on at around 6-6.5 ph

ashton420/7 When I fix the deficiency will the leafs recover since they are already kind of turning brown on the inside of the leaf?
