i have 3 plants 3 weeks into flower, all dutch passion #1. On two plants the pistils are already turning brown. the third which is doing fine is in a bigger pot than the rest. could they possibly be root bound and are under stress? Is it okay to transplant 3 weeks into flowering? Please help!
In answer to your question, you don't say what size pot, but regardless, yes, you can transplant in flower.
Just don't drop them on their head or anything dumb.
The one I have going now I moved at 3 or 4 weeks in.
