White widow dying on bottom third

I have an issue I can not figure out. This is a third gen clone, outside, compost mix for soil. It won’t flower, pistols are brown on the whole plant. Bottom leaves turn brown and sections are dying and falling off.

What kind of compost?
I would have to say that your compost soil is to hot for the plant to grow. Transplant maybe your only option at this point.
