So I am growing a grandaddy purple cross and im not sure it will turn purple with the leaves so green. I know that a strain will turn purple due to the genetics but If there isnt a lot of nitrogen then the colors will show up more easily and be more noticeable. I have been feeding here Pure Blend Pro Bloom with Sweet and none of the leaves are showing that they are getting less amounts of nitrogen. The leaves are really green and shes into about 6th week of flowering she has im guessing 6 more weeks. Is this normal? or what? anyone with an opinion will be greatly appreciated. GlaZed
