One thing just came to my mind that may make a difference!
A few threads back I posted something and sorry, but I'm not sure off the top of my head who it was but someone said:
->Don't use that water that comes out of my fridge because it has nothing in it for my plant and that I should use tap water....
->>So what I did was take 50% water from the fridge (that normally is left sitting out in a container for days until the container is done) and mixed it with 50% of tap water freshly poured, but room temperature.
When you say history do you mean everything that has happened in the past? or fill out that troubleshooting form? or both?
...I will give all the info I can, but am in a rush right now. Will post more info, detailed and time taken :thumbsup: later tonight.
