Heat damage? Disease? Deficiency? What do you think
(I'm in zone 9 southern CA, growing these in cedar planters, the chard sharing the planter with them is doing fine. Had some heat then some cooler temps & rain & now heat again- 70s/80s day time, 40s/50s night. Is it the weather or something else? This happened last year when I tried to grow peas too. They're sugar snap variety. Also if they do produce a pod or 2 are they ok to eat??)
