Fertilizer burn haygrazer

Put on some 32% liquid fertilizer on my haygrazer. It's about 6 inches tall and we have a bunch of rain in the forecast. Noticed it burned back the leaves some. Is this going to really effect it? Last year I got lucky and got a rain right after putting it on so it didn't have a chance to burn it. Wanted to put it down before planting but I dusted it in and was trying to minimize inputs as it was very very dry.
