Keep your chin up. I've had similar problems with germination and post germination problems this year. We have to roll with the punches and keep going.
I've been using and advocating the paint strainer bags for years. They work great.
You can use smaller bags but I find that there is a lot more blossom drop from less air circulation and constriction of growth of the branches, leaves and blossoms.
I'll continue to use the paint strainer...
