ok first off the purple has nothing to do with the nutes. Purple comes from the temp getting low at night. And yes some strains are more prone to temp changs but it is nothing to be concerned about. I would give your plants another 3-7 days and harvest. Just make sure you cure them for at least a week to optimize the thc content...:weedpoke::bigsmoke:



also just give them water no more nutes!!
