| The hydrophobic extract that is sold very commonly is specified as to be mixed with water only. I am sure that anything that specifies mixing with any amount of soap or detergent would be the pure neem oil.
All of my problems have occurred with great concern that both the heat and light were kept low after the initial notice of leaf mottling a few years ago. The GH was covered with additional shade cloth and the cooler thermostat turned down. The leaf mottling continued to occur in spite of keeping such conditions in effect for several days.
