Red or purpling stems, not the fan leaf stems, are P deficiency i believe. I have a couple strains that get them. They still seem to grow pretty vigorously, but I wouldn't try flowering until they green up.So I will add that I added a bit more p and k to my nutrient solution and then fed the plant today so I will post pics in a couple days to update on the red stem issue if they don't go away I would guess its either a sign of vigorous healthy growth or light intensity.
