Not sure if this is the color flower Pineapple Express should be but figure I would ask others. I never have grow before and I have one a month behind this one going so once it starts flowering I might be able to answer myself but with autos that might not be true due to genetics. !
There is definitely Purple in some Pineapple Express Phenos!!! She may or may not keep that throughout…What are your temps at??
I built a greenhouse so right now gets 80 s during day and 60 at night in northeast us.
I did a Pineapple Express about a year ago and it came out really purple as well
