Mexican airlines plant on day 26 with curled down sets of leaves up top...the plant seems a little stunted. I have been watering with just water and the plant is in a 5 gal pot with a happy frog/ocean forest 50/50 mix, but with 4" of ocean forest at the bottom and 4" of happy frog at the top. The plant seems a bit stunted compared to my others...what's wrong here?
