Ok first you are growing an indica. They usually form up like the pic I uploaded for you to look at. I watched your video. And you've got little nugs forming... BUUUUUUUT they should be WAY farther along in week 5 than they are.
So 1 main question. How old were they when you popped them into flowering?
Sub Q - what lights do you have them under?
Each strain has its own "rules". When you are growing a Sativa there are all kinds of things you can get into like LST, super cropping, etc. With Indica I have always grown for the single baseball bat monster full length cola. No topping. No LST. Nothing. Just grow bitch. But if you flower them too early, then you're going to get super stretch and the buds won't connect. No super sized cola. On an Indica plant, I like to get that center main stalk COVERED in veg growth. Like no gaps, shoots crawling ALL around it. The reason is 2 fold. 1) When you flower it, the thing is going to come close to doubling in size. 2) I want the shoots to catch the stretch and close in the gaps. The shoots grow close to the main stalk on Indica like what you are growing. They branch like a Christmas tree on a Sativa.
