I am having an issue on 1 plant that i just noticed. We have had lots of rain and cloudy weather for the past 4 to 5 days now and not sure if that is the reason. During the past 4 days i have stopped my fert drip program in worries of popping some more pumpkins today i resumed fertilizer. Is it Potassium Deficiency? Maybe Manganese Deficiency? I am going to get a soil and tissue test from this plant.
