Outdoor plant. Temperatures have been relatively comfortable. Low 80s during the day with daytime humidity around 35-45%. Nighttime lows are around 50 with higher humidity (obviously).
Researching before posting, it looks like heat/low humidity is often the culprit but some have said magnesium deficiency might cause it as well. Considering all of my other plants are growing without this symptom (including the clone of this exact plant), I am just concerned it’s something related to watering or soil. That said, they’re all on the same watering/fertilization schedule.
I don’t think it looks terrible, but I want to treat her well.
