Does this look like a mag deficiency?

Plants are 3 weeks old. Planted in ocean forest. Temps between 75 and 79. Watered with primo brand purified water. I did add a little bit of cal mag to the last couple waterings. I've had the calmag for a while though. I don't know if it goes bad. On 24h light cycle until flowering. Strain is strawberry gorilla auto and gorilla cookies auto

I'm not great at nute issues, but I don't see mag def. Fwiw, most people run lights 18/6 in veg.

Need more info. Lights, humidity etc. etc.
How much calmag is a little calmag?

Purified water? Why? What's in it, how is it purified? Ph?
 
It's almost ro water. Looking at the datasheet it doesn't really have anything in it and ph is 6.28

From what I understand, 24h is fine for autos. I was going to switch to 18/6 during flower.

I'm running two vivosun vs2000 in a 4x4. Humidity is around 40%
 
I think the problems started after using the primo water. Correlation does not equal causation though. My pH meter wasn't reading accurately and the data sheet for the primo said 6.28 so that's why I started using it. I ordered an apera pH meter.

Going back to using my tap. Ph around 6.5, I gave them some fox farm big bloom and some recharge so fingers crossed. Hopefully they recover.
 
Raise your humidity to 55-65 , and cut back at least to 20/4. I don’t care if its auto flowers or manuel flowers they need some dark not having any is a stressor.

How do you know your tap ph is 6.5, the reason I ask is that most municipal water is alkaline. They make it alkaline to cut down corrosion in their pipes.

Apera is good, but I'd use tap water and not worry about ph. 24 hrs light is ok for autos but I run 20/4, most people do 20/4 or 18/6.
