It might be a sign of phosphorous deficiency. It usually shows up in flowering or during cold temperatures, because the cold inhibits phosphorous intake. It might also be the strain.

Thanks alot, how would I go about correcting a phosphorous deficiency

give your plants some bloom fert or anything high in P

purplish leaf veins are also a good sign of a phosphorus defficiency

thanks guys i'll check for purplish veins but it very well could be cold temps

I would go with cold first, what are your temps at night?

Cold temperatures (below 50F/10C) can make phosphorous absorption very troublesome for plants.Not enough Phosphorus causes slow growth and causes the plant to become weak. Fan leaves will show dark greenish/purplish and yellowish tones along with a dullish blue color to them. Sometimes the stems can be red, along with red petioles that can happen when having a Phosphorus deficiency. This isn’t a sure sure sign of you having one though, but can be a sign. Some strains just show the red petioles and stems from its genes.
