number one cause of purple stems and ugly looking plant. high ph. over 7 in soil . high ph will lock the lnt up it will not absorb fertilizer. make sure its between 6 tp 7 soil 6.5 is best.

the yellowing is on the new grow, which suggest lock out, check your ph
its not magnesium
and like they said the purpleing of stems is nothing to worry about

purple, redishbrown stems are fine, thats not mg stuff at all, nor does it look like pH...not sure if this was stated before, but dont just add salts (or lime on the vice versa)...check pH of the run off water, and do it like 3 times to gain an average before trying to adjust stuff, just my opinion tho. PEACE and Goodluck!

Looks like a problem I'm having with 3 of my babies. I fed one of them calmag and she seems to be recovering. Here is before and after pics. The red/purple veins have started growing green on the new leaves after about a 10 days and 2 feeding of calmag.

marijuana stems turning purple may be an indication of a deficiency in phosphorus. you can correct this problem by feeding your plants with a phosphorus rich fertilizer. if growing in a hydro set-up, simply add the phosphorus laden fertilizer the next time you fill the resevoir.

I figured out that my ph meter was faulty. Is was a ph issue. I think causing some lockout.
