Sweet Potato Growing In Zone 9

Question

I planted slips back in early June. They took right away and they went off, but it feels like all the plant’s energy went to growing the vines because when I harvested the potatoes on October 9th, they were all incredible small (as was the overall number). What did I do wrong?

Answer 1

This will signify a lack of phosphorus and potassium, or too much nitrogen.
