I have been growing in Florida and my plant is not doing too well. The leaves are turning yellow except the vein area and the very edges are turning brown. Growth has halted and some leaf loos has occured. This seems like a nutrient deficienty but I have been giving it Dyna gro foliage pro 1tsp to 1gallon ratio. The potting mix is a 3:1 coco coir perlite mix. The pot is roughly 8 gallons with 6 1/4in holes for drainage. The plant is kept out of the heavy Florida rains and only gets its water from me. The water I give it is plain tap water with 1tsp of dyna gro. I plan on testing sool Ph soon. Attached is a pic of the plant.
