I'm 2nd week in of 8-10 week flower and noticing some fan leaves stems are purple . The plants themselves look fairly healthy .but I've read online it can be caused by some sort of deficiency or stress

pH levels have been between 5.8 -6.3 .
Haven't overfed nor underfed
And Feeding once a week and watering once more if needed (pH water only)

My set up is 480watt qb 12/12 temps 26°c with about 50-60 % Rh

Lights off oil filled heater bringing temps to 25°c an oscillating fan and a clip fan 60% Rh

Leaf stems purpling is pretty common. Stalk and branches purpling, not just veins is what most are talking about as a deficiency

I usually veg till they show sex. Dont use fem seeds cuz i am cheap.
6 to 8 weeks veg.
I have a tiny 2x2.5' tent with around 130w of led
I think the plant in that pic was 2 gal. I repot a week or so before going 12/12

My tap water is 250- 300ppm would not be sufficient? I have cal mag . But I assume that would cause an abundance of calcium
