What's up with my FLORIDA BEAUTY in SEMI-HYDRO | Send help??

G'day, you mob! Today, I try take a look under the skirt (at the roots) of my Philodendron Florida Beauty. She's been looking rough as guts recently and I have a feeling it's pH and/or nutrient related. Let me know if you have any thoughts in the comments below! Instagram -   / petevsplants
