Im currently in week 3 of flower and most of my leave are green and healthy but noticed a few that look like this. Is this calcium deficiency? And are these purple veins the result of a toxicity ?

Im running hydro so I have control over my ph. My ph ranges from 5.8-6.2, mostly 5.9

I'm a hydro grower; your PH is good, try to stay under 6. Purple stems can be genetic, stress or light burn usually. It could be a calcium deficiency, they look like the right type of burn. Likely not light burn week 3 in flower. I like this link; it has lots of pics but it's kinda long. https://www.growweedeasy.com/marijuana-symptoms
