Thanks very much for the thanks... I love helping folks who WANT to learn and who are willing to do the work. You are both.

On reflection I think you have too many roots but they are not healthy and so are dying off and/or rotting and affecting the strength of your stems. You have nice large plants but had several "root issues" along the way including your ph issues AND overnuting which burns the roots too. Taping your stems WILL help and using rhizoT and cannazym wiill help as well as long as you have good drainage through the red buckets. Otherwise the odds are much more against a finished harvest without problems.
