I most definately do not have purpling from deficiency. I have grown so many intense pure purple strains and played with others and temps, nutes etc and for most part its all hogwash. If u really F up a plant so bad you cause ALL of its white pistils to turn hot pink you would see other negative effects complimenting it. A truly healthy purple strain is a very beautiful thing. Many of them all have the traditional purple afghani grape candy like terp profile too. But some dont at all like Sativa heavy Chitral kush SweetSeeds company uses to make black cream, dark devil, red poison & the like.
Pineapple terp plants excite me too. When you get that phenoe of pineapple kush that literaly smells like fresh cut pineapple in its raw form; making sum intense tropical flavored live resin dabs that will make ur cheeks pucker. To this day the best tasting bho ive tasted was pineapplekush live. Made from fresh buds only 12 hrs frozen, blast and then try sum dabs right after its done purging while its at its most fresh state. bAaam!
