Not sure what to do here. This is my first year growing corn, they grew normally. But here's where the issue is. After they tassel maybe a week or two later the first ears emerge and they get pollen, but a week or two latter the second ears emerge. But the tassels are drying up, when i shake them almost no pollen comes off. What should I do? I gave them blooming fertilizer but I imagine that wont do anything. Without the pollen the second ears will just go to waste. I know your supposed to grow corn with a lot of each other together, and I though 30 was enough, but I guess not. Is there anything I can do?

That is normal. Late emerging second ears rarely do anything. When you get multiple useable ears on a stalk, they normally appear almost simultaneous.
