Hello fellow Philodendron Fam. I've had a Variegated Billietiae for almost a year now. From what I am reading, they are generally a fast growing Philodendron. I received mine as a lightly rooted chonk with one leaf and another leaf that was getting ready to unfurl and since then has only grown two additional leaves with the third growing now. I have it under a grow light and it also gets very little direct early morning light, planted in a soil mix that I have all of my soil plants in, ambient humidity ranges from about 45% (rarely that low) to about 70%. Are there any tips or tricks that someone might have about something I might be missing? I'm not a huge advocate for semi hydro in the sense of me having all of my plants in it but as I encounter issues is when I usually try the semi hydro route. "If" I went in that direction, would leca or pon be better for this particular plant?
