BigBill said:I think that your growing conditions are fine.
Any insect damage I can think of does not look like what your images show. Same for fungal or bacterial issues. Hence my concern. It could be insect damage from the underside of the leaves but then those yellow kind of circular/oval stuff I see does not look like insect damage. At least not that I can recall in all my 45 years.
It is not heat stress or cold stress plus your temperatures are fine.
so I am thinking about getting it tested either by getting a testing kit from Agdia or sending it for testing at a lab.
