Fertilizer Question
Hi have a question about fertilizer. I use the MSU type fertilizer, once I mix it with water, how long is it good for? I like to keep water in buckets for dunking mounted plants in daily. I keep the same plant to the same bucket of water so I am not mixing the orchids in the same water. Also, is it okay if the top layer of my MSU fertilizer in the container turns a bluish color? I was wondering if it means the part that turns blue will no longer be good after a certain period of time. Any advice will be much appreciated!
