Nitrogen starts yellowing at the bottom, if you have abnormal growth or yellowing on new growth it would be calmag.

I can't see it clear on the photo. Make sure the PH pen is calibrated, also take a look at the new growth after you added the Calmag

Most likely nitrogen deficiency. I know nothing about hydro though, feed needs increasing if it's draining the leaves. It's basically eating itself to survive

Deficiency or Burn?All these girls in manure compost/perlite mix. Healthy through veg with minor Magnesium deficiency in the beginning. Been feeding 3ml/gal calmag occasionally, and 1/2 cup banana tea I made 1-2x a week. Waterings have been at 6.5, just lowered to 6.2. About 1/4 gal/plant 1-2 days.
