The Great Grow Experiment

Plants were watered with plain tap water yesterday (7/1) with a little under a cup of water each. On their 6/28 watering they were treated with a small sprinkle of mosquito bits and some additional mycorrhizae. I'm not sure how often to add these to their diet, so input is appreciated. I also have Neem Oil for pests and a sprayer that I'm not entirely sure when or how to use, but it's here when I need it. Slight yellowing and curling on lowest leaves, so I picked those off the other day and the plants seem happy. They'll get their first meal (1/2 tsp Bud Bread with 1/2 gallon water split between them) on Wednesday (7/4). Plant #1 has a crooked stem, making it difficult to measure her true height, but her leaves are growing full and stretching upward. She has noticeable new growth near the base of the stem that I hope will become a strong additional stalk. Plant #2 looks a bit like a palm tree at the moment, but I think I see a tiny baby leaf starting to grow near the base. Her leaves are growing slightly unevenly, growth favoring the right side. Neither plant has darkened much in color.
