There are lots of seed banks selling ww seeds but they are mostly relatives of ww not pedigree .
More than likely you have some unusual cross of ww.
Root rot is from too much water and not enough air (oxegen) to the roots.
If your soil is wet or very moist let it dry out , better a bit dry than wet.
Root rot will kill the plant usualy a yellowing from the bottom up and leaves dropping off on the way.
If the plant is healthy then keep her going till the end .
If you force dryed the bud that you tested for tast and potency then that will have a harsh cloraphyl tast like a camp fire in you mouth.
So when its ripe dry it properly " i take it you know how " and than give it a go.

Good luck .
