Looking at the pics the symptoms would suggest Potassium, but one of the pics suggests there may be a smidge of Calcium deficiency there as well.

If you aren't already, I would be adding a liquid seaweed extract on a regular basis. If you were here in Oz I would suggest a capful of regular Seasol per 500L per week.

If your water pH is below about 7.0 then you could add Calcium hydroxide and Potassium bicarbonate in about a 4:1 ratio. A good starting rate would be 1x level teaspoon of the Calcium hydroxide and a 1/4 level teaspoon of the Potassium bicarbonate per 500L.

I don't think you'll find Seasol in the US. Maxicrop is probably your best bet, if possible get the version with Iron. You can also buy seaweed extract in powdered form, that may be an easier and cheaper option.
