Salutations all! Hope all is well! Been horrid cold here, lows in the -30 to -40 for a few days

Stuck inside for the most part due to sickness so hasn't been that bad to endure

That also allows me to binge watch GOT(never watched it b4,) love being able to watch a full series without having to wait a week to see the next episode!
Onto the current happenings of the tent!
So, 4 days after the flip, cal deficiency(pics of photo)?

Is there a possibility of over dosing w calmag whilst trying to correct it?
I've been noticing pretty much through the whole grow of both systems, the ppm stays pretty consistent. Does that mean I nute locked them?
The dwc auto drinks about 3/4 gal a day and seems to be doing ok?

What a lovely smell when I open the tent door

Currently my mammoth 8 mint led is 23 inches above the dwc canopy and at 90% I'm thinking maybe I should lower the height and the %? I'd be more than happy to take more pics if need be
Tent stays around 78° and 60% RH with vpd around 1.2 light on. Keep the dwc around 500 ppm, rdwc 340. Been adding calmagic when I c what I believe is cal deficiency.
