Strange issues with plants

Hi guys!
I am again having strange issues and I’ve been unable to determine what is going on exactly so I am calling for your help! :)

3rd week of veg
Soil - Plagron royalmix
Light - 200w LED
Watering - every 2 days/2l per plant
7l smart pots
No nutes yet as the soil is pretty rich in nutrients.
Tap water at 7ph

so the issues I’ve been seeing are purple stems, and although the leaves are green the veins and the stem are purple (on all plants)

and today I’ve noticed brown spots on somes leaves (only on one of the plants). All other plants are good for now.

Some pictures:

Thanks!
 
Purple streaking of the stem is usually caused by sulfur deficiency. I know low temperatures can also cause this as well. As for those dots, they could be signs that you need calcium.

check out this resource for info on nutrients.

Thanks for the replies guys it could be underwatering and feeding, I’ve not added any nutes to them but I’ll start to now.

I’ll also give them some calmag.
 
overwatering*
sorry I misread

I’ve given them a good dose of nutes and some calmag.
 
I don’t know your soil
Does it contain micronutrients?
is it considered organic
I hate that Calmag gets over used
It has nitrogen that wrecks plants in flower and hides issues in veg
My best advice on Calmag is a flowering one without nitrogen or none at all
 
I've seen a kagillion purple stems over the decades , always had healthy plants. I even get a purple plant " once in a blue moon". I think it was just genetics. I don't think the purple is the cause of your leaves yellowing or spotting.
 
Alright so I think everything is okay again and it was lack of nutrients. After upping the dosage and increasing the watering a bit (I use smart pots), they went back to normal.

stems are no longer purple and leaves are also spotless!

thanks for all the help guys! :)
