This is the first time I grew a lotus and the plants below were grown from seeds about 2.5 months ago. They are currently in a couple of tubs. Over the past few weeks, the edges of the leaves have been drying out. Is this natural? Is it from the South Florida sun or do I need to fertilize more frequently. I fertilize every 4 weeks and the plants get atleast 8 hours of full sun per day.
Also I have noticed some of the leaves are not the dark rich green color as they were before. They are a green-yellow color. Any suggestions as to why?
