Oh, you mean where you helpfully pointed out that your petiole reading method is irrelevant and wrong in many cases?
PURPLE = STRESS. It does not fucking mean "needs nutrients".....though it CAN be a result of that....because nutrient deprivation IS a form of stress.
Look at the very pictures you posted. Anyone with eyes, who has looked at enough plants, can tell just by the color of the leaves that the third plant needs nutes. Compare the three pictures! Do you not see the difference in shade and luster? The purple shit is irrelevant. That could be caused by temperature, by light, by genetics, by a hundred other factors, as I already stated in my first post, before your dumb ass blew this up into a (yet another!) shitfest of jackassery.
Listen to what we're fucking saying. It's clear you've probably never popped more than 20 cannabis seeds in your life. Stop coming into threads and trying to argue knowledgeable people into the ground about stuff they have firsthand experience with, only to discover (surprise!) that you were a moron all along, long after legions of newbies have been misled by pages full of your loud mouth and lack of knowledge. (This is why they call it "knowing just enough to be dangerous.")
Stop googling shit on the Internet and copying and pasting like that means anything. Anyone can do that. It takes someone with an actual clue to think critically and understand what they're reading.
when you need to resort to language like this you demonstrate the need for moderators.
