Hi All,
I noticed these yellowish spots on the leaf margins and tips look burned. It looks to be isolated to the leaves midways up on the plant. The very top leaves look great.
This plant is about 2 weeks in from the start of flowering (pistils). Overall it has a nice green appearance.
What do you’all think is the problem?
