I’m almost 3 weeks into flowering, never had any problems, been lucky for my first grow. I inspected the plant today and noticed about 3 leaves with this burnt look to them, where they were brown and dry and black. Just on part of the leaf not the whole thing. Leaves were lower down in the shaded part of the grow, and farthest from the fan. What could be the cause? First time ever seeing something like this. It can’t be a fert issue because the rest of the plant is looking normal and growth is fantastic. Well, there are a couple other leaves that are turning inside, like the spikey ridge of the leaves are turning downward. Just a couple.
Here’s the plants so you can see they are healthy looking.
