Nitrogen deficiency or could it be nothing
In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

Long battle with deficiencies.
For a week i have been fighting deficiencies , the ph seems fine. Part of the problem was fixed by calmag but how it seems to be something else, maybe someone can help me identify.mid to top leaves affected. Also overall heat could be a problem (as temps outside rise)

Spotty leaves
My bottom 2 leaves have a few very small yellow spots. I've heatd that I should start by checking PH and then go from there. Anyone have any suggestions if it is PH?

Bloque de nutrientes?? Ph?? O falta de calcio y magnesio??
the bottom leaves have a yellow color, the smallest ones fell off completely. The upper leaves have yellow tones at the tips. I'm using biobizz nutrients and following the chart exactly as indicated in all the waterings. Could it be nutrient lockout?

4 days without water
I had to leave for 4 days this past week. Gave both plants H2O before leaving but I came back and one of my plants has some ugly yellow and brown leaves. Do I need to do anything to correct this or just get back to my routine feedings?

Deficiency or Genetics
Would you guys guess the yellowing on these leaves is more natural coloration from genetics or do you guys see something more? Plant is definately small but seems to be healthy and buds keep growing.

Quickly yellowing after possible over watering
That escalated quickly, within 24 hours we have lots of yellowing in lower center leaves on 1 Tastebudz and 1 Ethos: Adding cal mag to next watering. Would cal mag be better or Epsom salt at this point? Would a bloom tea help?
