Purple stems on autoflower

Hello everyone thanks for your help.

Problem: purple stems
Age: middle of week 6 from planting
Temp 76-84f
Humidity 60%-65%
Lights: mars hydro tsl 2000 at 25 inches
Coco coir + super soil(living soil)
Just added a tower fan
Added a little Epson salt about a week and a half ago. Plant keeps on growing but this purple stems are bothering me and don’t seemed to get better. Please any suggestions are much appreciated!

Last week did my first watering with some nutrients(recommended by local hydroponic store) and only 1/3 strength every 3rd watering recommended by living soil maker(Apotforpot) since soil is already “hot”.Posted pic of nutrients. Should I increment the portion? Have been told is magnesium deficiency. What is your opinion on this beauty? Thanks for your feedback


Also when watering without nutrients ph is 7
With nutrients 6.3ph
Watering to Maintain about 1/3 of its weight as if it was fully soaked

I wouldn’t worry about purple stems. A lot of indoor growers have them.

@eddy360 I know your post was from June. I have healthy plants with purple stems. I added Epsom salts last week. How did they turn out?
