A week or two back we had a few nights dip into the thirties here in Illinois. My NL and Blueberry's are both getting some purple and bluish hues to them as a result. The average night temps for the next two weeks will be in the 50's. My question is whether the color hues will keep coming out or does it take consistent colder nights to keep adding color as the plant packs on weight? I have noticed in the past that certain buds will be totally green on the out side but I will find some purple inside as i break it up. Is this possibly from high and low temperature spikes during flowering? Sorry to hijack, it's just a question I have had for a while on temps.
