Ok so this is my second indoor grow so i'm definitely still learning. I am currently in 3rd week flowering out 6 Purple kush clones i got under a 600w hps in a 4x3x5 box i built. I feed Maxibloom, and liquid koolbloom my night temps have been getting down pretty low for about a half hour the past few days. Just wondering if that would make my plants start to get a kinda purple hue to them? And would it be a good idea to start pulling some leaves allow some more light to get in? I have never grown purple kush before and any help or tips is much appreciated. My grow space is getting pretty packed.
