purple stems???????

hey i know ive read ither questions about stems being purple but i forgot if its ok or ba dor what it mmeans exactly. plrease help??? i just started nutes 2 days ago and they grew70% larger in A day and a half!! i just noticed that thew stems r a nice purple color but not sure if thats good or not lol! thx in advance

could be cold temps, otherwise i believe its fine.

na def not cold in there nothin else???

Purple stems could mean either its a N,P & K deficiency or low temperatures.

I think it's lack of "N"........i remember seeing that on here somewhere.

the only purple on my stem is where the plant is closest to my exhuast fan so im assuming its cold??? but then again i think i have a nitrogen deff. could purple stem result from both??

yea but usually if its temps the leaves would be turning purple as well. try feeding it

whats the strain? picture is worth a 1000 words.

It needs food no doubt
