What's wrong with my Boston ferns?!
*there is also one NON Boston but I'm not sure the variety
I keep these in a greenhouse setup with bright light, 60-90% humidity most of the day with temperatures between 60° and 90° Fahrenheit
This damage appeared suddenly out of nowhere, one is hanging, one was on a plant stand, both are fairly root bound in these pots they came in so in other words they don't hold a ton of moisture this is in Phoenix Arizona so the ambient humidity outside of my greenhouse is extremely low and we get a ton of sunlight!
These turned this way over a very short course of time, I've applied one round of Miracle-Gro fertilizer about 3 weeks ago so I'm not sure if that's what caused this but I threw them out as they were only two for 20 bucks and didn't think it was worth the risk to all my other plants
