.5 ts to 32oz water FF big grow (burn?)

I just watered my 2 week old dirt 2 gal plant with .5 teaspoon of fox farm big grow in 32 oz of water. The pot was fed well the day before and most of it drained out the bottom. Is this too concentrated of an amount for a 2 week old plant?

I'm just waiting to see how it takes to the nutes. Its doing so well. Hope it doesn't burn.
