Ive read the deficiency pages on Mr. Texas's website and Flying Dragon nursery- not sure what is going on. My new Meyer leaves are huge, and a bit rubbery looking. Not exactly the definition from Mr. Texas for Cu deficiency, but closer to the FDNursery definition.
Some older leaves are yellow and curling (did that this winter when it needed flushed- perked right up. but weve had several hard rains recently)
I just gave them some organic fert, ive got at least 2 more good months outdoors for them all here.
the new leaves are on the left, in my hand.
