Burnt the tips of white hairs. Big mistake?

I'm week 3 into flower and I moved my light a little closer bc I run led and it wasn't too hot. Well I fed today and the tips of some of the white hairs are a little burnt. Did I ruin the little yeild I have?

I’ve had girls that the hairs started turning about a month in. Nothing should be ruined. How close is the light? Details help and so do natural lighting photos.
