Below is a photgraph of a community pot (2 inch square) of Pinguicula -- Yucca Do 1713, small plants. Approximately 1 week earlier, I had dusted some of them with a light sprinkling of "Freeze-Dried mosquito larvae" (Bloodworms) which I had ground to a powder. After dusting the chosen few plants with the "Bloodworms" I lightly spritzed all the plants with my usual fertilizer solution. I continued to spray them lightly with my fertilizer solution every few days, but did not add any additional "Bloodworms". See if you can identify the affected plants.
