A lot of my stems are turning purple. Some are more solid and some have vertical purple stripes. The color extends to the veins on the bottom of the leave. I am 12 days into 12/12. Is this a nitrogen deficency and if so what is the fastest way to fix? If not nitrogen, any guesses? As always any help is much appreciated. Cheers.
I go hydro are u dirt or what? I know in my grows i always see this, in fact today i saw one stem looked like this - - - - - Tomorrow it'll be a straight line. Some strains are prone to turn purple. Now with pics it would be better diagnosed.i have grown for 9 yrs but i also believe the man who knows everything knows nothing
phosphorus def it can be caused by lockout, lack of ferts & cold temps temps below 57F stop the plant from growing & phosphorus is the first nute to show the def
