I have healthy sour diesel plants 7 weeks into flowering the fan leaf stems are turning purple it is some what blotchy as in not the whole stem and some purple dots below the purple streak. how do I tell if it is a deficiency, cool nights,or natural to the strain. Will it be a different pattern for different issues? there seems to be no leaf issues or any other negative signs on these plants.

this is what Im talking about oh well dont know how to add the pics. so you cant see.
 
Purple sTems can be a couple of things firtly it could just be plant genetics(and most likely) but it could be stress or just ur leaves starting to die of as u get closer to hrvest

Ya those plants are just about to be fired up....What's your PH and PPM. It's a little late in flowering to worry to much. But flush and check. Looks like fert curl....

My ppm has been around 850 I had it higher but they seem to like it low the highest was 1400. running the GH expert recirculating schedule PH i let fluctuate freely beetween 5.5-6.5 with a goal of 5.8 I only adj. to 5.8 when it goes to 5.5 or 6.5 ;-)
