I've been growing these guys for about 4 months, and I'm starting to notice the leaves turning yellow and dying. I removed several dead/dying leaves before taking the photos so there were more dead/yellow ones on the plants. I was wondering if they were suffering from nutrient burn before adding any nutrients to the water. I've started to notice a slow down in growth, and was gonna add some nutrients to help spur growth because I want UGE nugs. If you can help me please do, Im new to this and are trying to learn. Also if I posted in the wrong spot Im sorry this is my first post.
