Is it deficiency or nute burn?

[Halfahero]

I can't tell if it's cal- mag deficiency or if it's nutrient burn?

Check your PH.

 

[Rootsruler]

What are you feeding? How much? What pH? What stage is the plant in? Week what?

Is that a spider mite infestation in the last pic?

Might be a PH Problem

7.1 a couple of days ago

 

[Rootsruler]

Try hitting 6.5. Also, test your run off pH

The plant is in a mix of coco, worm castings, perlite, and soil. Up until about 1 month ago, I was not feeding much(just watering) and started cal-mag right around flowering 30-35 days ago. The last 3 weeks I have added Armor Si, very low concentration. Checked PH of run-off after flushing and was at 7.1. Plant is flowering and in approximately week 5-6.
