Dish soap is used to get the Neem oil to emulsify into the water and it will be found in the instructions on most Neem containers; the same as getting the vegetable oil to emulsify into the water in the recipe that Hydroholic suggested. The only time I have not seen dish soap in the mixing ingredients on a Neem oil bottle is when it was already added and the container is a "ready to use" (spray) bottle.
This is the first time I have been able to read this thread and I have the feeling that if you turned off the grow lights and used sunlight or a white room light and the camera flash the white tips would look more yellowish. @Greenlizard brings this up when he mentions that the light looks like the Blurle LED lighting.
I am surprised that no one brought up the major leaf problem that shows up in the 4th and 5th photo in message #6. Most likely the demise of the plant happening this fast could be related to whatever is causing that.
