Canadiananswered grow question 5 years ago From the pictures is a little hard to tell but the leaves are very Green in fact they look dark green and many tips seem to be burned if you see some the buds of the lower branches having the same yellowish colour that definitely means nutrient toxicity( nitrogen) if you do not see any more yellowing in the bottom buds (popcorn buds) or older leaves then chances are it is light burn.
Hope this information help you out good luck with your garden have a happy grow
