I can't find this info anywhere. Is Durban Poison supposed to have a purplish color to it? I'm seeing some purple streaks on the leaves and stems. Also on the males the little dingleberries starting out are all purple. I started the plants outside to take advantage of the last few rays of sunshine and also to start them out flowering to cull the males before they go under the lights. The last few nights have been pretty cold, down in the lowers 60's and 50's. Does the cold snap make them purple? Just wonderin, they seem to be growing fine.
