had same thing with purple urkle. think it may have been really cold temp when lights were out as night time heater wasnt working. could this have caused your colour change?The prices really depend on who you get it from ultimately..
I don't really buy weed because I grow it year round but the prices I sell to my friends of good stuff are usually 10-15 a gram, 40 a eigth maybe 50-60, 300oz, 1800 1/2 pound, the bud is always anything good likehaze,Whitewidow,jackherra,M39,Blueberry kush, GDP and I have several purple urkle going right now they are looking very nice ... except one turned a funny color red during the flowering stages? Not really sure what that's about yet but I'm looking into it.
Anyone have any ideas? I'm dumbfounded.
