Thanks Johnei!The beginning of potassium deficiency?
Overall main base nutrient low.
(Macronutrient issues.)
I think I saw Potroast post that if the temp added to the humidity is over 140, then don't spray. That would mean I could never spray. But most folks spray at night or when it's cooler.When spraying plants, do you have to consider what the temp feels like do to humidity? Or just actual temp?
