The only spray that plant ever got was some pyrethrin weeks earlier. The plant is a OG Kush mother that's about 7 months old. It was inside until the beginning of June. Its hard to get a good picture. That's a 6ft fence.
Think it was just direct sunlight. I picked off the affected leaves and it hasn't come back. The plant is in a pot so I also rotated it. Seems ok for now.
