Hi all -

The top leaves of several of my pole bean dried out and curled up as of yesterday. I used my moisture meter and watered them - they were a little wilty and the meter said it was almost dry. There is no evidence of pests - spider mites on other leaves but these leaves are perfectly green and not damaged except they are dehydrated - like crispy.

The plants are about 8 inches tall - and we had a hot day yesterday. My first time growing beans...

Anyone recognise this? Much thanks!!!
