White, hard colas on my Gold leaf

From a fellow grower: My Gold Leaf was looking so awesome and so I chopped it today. That’s when I noticed these white hard areas inside the top cola. Do you know what this is and what it means for the rest of the plant and my other plants nearby?

Looks like light bleaching/ burning to me I bet those were closest to the light and they look like foxtails too which happens as a last ditch effort to protect buds from high light
