On this side I have yellow squash, beets, carrots, pumpkins, leaf lettuce, corn, tomatoes, and spinach. I also have a couple of gladiolas bulbs that I had left over from planting in front of the house. Currently the plants are starting to turn yellow. I'm assuming that it's a nutrient deficiency since I only have 2 medium tilapia in the tank so far. The algae probably doesn't help either since it's eating up the nutrients in the water before the plants can use them.
