Thanks for your input. I follow a regular feeding regimen in veg (White Widow problem) and light feeding regimen in flower (Hindu Skunk and Kushage). I flushed WW for about a week and she didn't recover. Roots looked white, solid and very healthy but growth has stopped completely. I am at a total loss here. I suspect some kind of an ozone problem. What do you think? I have a very good air circulation but I donâ??t do any air exchange.

What are your thoughts regarding Hindu Skunk and Kushage?

Your thoughts and suggestions are greatly appreciated.
