I think this is a potassium issue. Iv amended the soil and also added kelp and a teaspoon of alfalfa meal. Wondering what you all may think.

If your talking about the yellow tips,that's generally the first sign your soils nutrients are a little to high and its starting to burn the plant. I'd check the ec/ppm on your runoff to get a good idea how strong your soil is.
