I have been getting completely red stems on this one strain I have acquired recently. At first I thought it was poor P uptake because my soil was a tad cold and wet. However none of the other plants are the same and I am starting to think its excess nitrogen as the leaves are pretty dark on those same plants well the other plants are light green with no red/purple in the stem. I don't see the same problem in flowering with the same clones. Any pictures would be great.
