I went in and checked my Gardener who tended plants yesterday morning. The keg in her pack still said Greater poison. I then filled a bottle from it and it changed to deadly poison. The bottle from it, labeled Greater Poison, went back into the keg fine. The next bottle came out deadly poison.
I tried tending an orange petal plant with the deadly poison keg. The plant took two doses as if it were greater poison. The keg weight did not change until I filled a bottle from it again and put it back in, whereupon it showed the two dose lighter weight. I repeated with a second plant and the same thing happened. Both plants are at the 1/8 resource stage.
I double dosed the two plants with greater heal & greater strength potions. I'll add to this post tomorrow whether the plants get sick from two un-needed poison doses.
The plants are apparently seeing the keg contents as greater poison.
Keg being used was in a backpack inside her main pack.
========================================
Plants tended normally with the keg labeled deadly poison.
The keg returned to the normal empty keg text upon running out.
The next keg stayed labeled greater poison until I filled a bottle from it. Then changed to the deadly poison label.
The bottles labeled deadly poison give a greater poisoned weapon.
The bottles labeled deadly poison give the greater poison pain message when drank.
(I used to do service calls over the phone. The more info about a problem the better.

)
==============================================
Both poisoned plants survive so far. One mildly & one severly poisoned. Both showing healthy.
