reddish tips on preflowers?

My outdoor plant is about two months old and it started showing preflowers about a week ago. I went to check it today and some of the preflowers have reddish orange tips. What does this mean and should i be worried? Thank you in advance for any help

Do the tips look burnt or have they just changed color? If they do not look burnt id say that it is a normal occurance with the variety your choosing to grow. If they look burnt the more than likely it is nute burn, unless you haven't fertilized in a while. I wouldnt be to worried unless other symtoms occur.
