New Grower Potentional problem ?

[psychokiller]

I am on my first grow and since i am growing 1 plant i am overcautious so maybe this is nothing.
Some important info:
Strain: RQS blue mystic(photosensitive)
lights :120w(real) led panel
temp day: 24-27, Rh day :45-55
temp night: 19-22, Rh night: 60-75
Flowering day 14 vegged for 30 days
Growing medium:biobizz light mix,perlite,cocofiber (70%-15%-15%)
Nutrients :biobizz grow ,biobizz bloom ,biobizz top max, AN big bud. Feeding every watering(watering 4 times per week) dosages as suggest by companies.
Water: Tap water sitting out for 2 days
PH of solution : 6.3-6.7
PH of runoff : 5.5-5.9


Today i noticed some red-purplish color on some leaf stems mainly to those closest to bud sites and some red veins to these leafs as well

1.

2.

Also i am seeing some very early signs of over fertilization

3.
A full view of plant seems really healthy to me

4.
Is it possible the color on stem leafs changing due to over fertilization ?. IS it a sign of an incoming problem? Early signs of cal-Mag problem? it's just genetics? Or it's totally normal?

It don't look over fertilized and its not nute burn, the purple strips on stems and leafs is a mag issue, simple fix, just get some normal epsom salt add it in at 1/8th of a teaspoon per every 2 gallons. Overall it looks really healthy.

Good luck, seems like you are on the right track
