Week 4, browning buds

[Cpgribble]

Hey guys it's my first time growing and some of the buds are getting brown on top. Could this be from nutrient burn? It's the start of the 4th week so any information would be great!

Not a pro, but it looks correct to me!

If you are referring to the brown I circled then it is totally normal:)
