Exactly what I've read zip. The potassium deficiency is cited in this University of Maryland paper on yellow shoulders. The stressed plants stop taking in potassium.
" Yellow shoulders is also a varietal problem, as some varieties are more prone to the problem than others." Mine's mostly the pink's and all in the hottest end of the garden. Thirty plants same fabric pots, same measured solution of ferts and water. The difference for me is plant type and location in the garden, most do not display the condition at all. https://agdev.anr.udel.edu/weeklycropupdate/?p=3457 Last edited by Ricky Shaw; August 3, 2016 at 09:26 AM.

They are getting a complete hydroponic solution, although I suspect the media is holding too much water, which can cause some uptake issues.
I am picking before fully ripe, and our heat has passed, things are looking much better. |

Sorry, didn't know you do hydro. You could add a little MKP to your solution. It's crystals that dissolve in water. Picking early is probably the only salvation for fruits that are already fully developed. Glad to hear things are getting better.
