Madman they look healthy but I don't see any preflower yet. Northern lights autos tend to veg awhile from what I've seen. Yellow tips are just some nute burn but it's mild. I do not defoliate until they are 3 weeks into flower and then very sparingly. Those young plants need those leaves. I tuck them under the canopy and do lst. My sour stomper has over 30 tops and looks to be a 4+ oz plant. can see her fan leaves still feeding her at 64 days.

sounds like nute burn but you seem to be on top of PH and watering. try calibrating your PH meter to make sure it is accurate. You are growing in supersoil and typically those soils have nutrients that will last 3-4 weeks so the likelyhood of nute burn is present. You did a flush which is good and don't back off on the nutrients during veg...that's when they need them most.
Just ensure that every other watering is a flush with properly PH'd water and use nutes as directed. You are on top of the humidity but it really should be 50-60% in veg.
FYI Calmag IMHO should be optional if you are doing everything else correctly because the brown tips aren't a calcium deficiency.
As far as defoliating...you can but training the plants works well too because the fan leaves are like solar panels and they are used to give the plant energy to grow. Especially strains like Northern Lights...they love lots of light at least 19/5 or more and check the manufacturers recommendation on the height of the light source. 31 inches is a bit too far away assuming that's measured from the top of the canopy versus the top of the pot

Sour stomper is memphisto. Check out my journal.

I would not leave them to dry out. at 25C and a 10% runoff they should be watered every 3-4 days. the plants are 6 weeks so I would try moving the light to 24 inches as the flower stage likes more light. You could run 20/4 but it's not necessary at this stage so 18/6 is fine.
Yes definitely get a good PH tester because that system you are using is not very accurate IMHO. Make sure the PH tester is properly calibrated. Look for one that is easy to calibrate...some are more finicky than others (Preciva)
