I don't find blight to be a problem in a greenhouse. I have had an occasional suspect leaf that is immediately removed. What I find is a problem later on is botrytis or grey mould.You need to keep a careful watch and remove any affected leaves before the fungus reaches the main stem.
I have also been plagued with tomato leaf mould that spreads very quickly through a greenhouse. I suspect it arrived via infected seed. I have one greenhouse which is clear this year so will save my own seed from plants in that greenhouse. In the polytunnel, it is starting to spread and I think it is from some marmande plants so I'll get rid of any of those seeds I have left.
