I agree with @Brandon , looks like calcium deficiency.
Thanks Buddy for helping. Order BioBizz Cal/g today
Looks like it could be cal defense but you would need to do a ph runoff test to make sure it’s not nut lock out but I would definitely start using cal-mag with at least every other watering hope this helps
Yes
Is the rust color on the lower part of the plant?
Do you use cal-mag?
