Is this going to be a problem?

Just noticed this, the plane has shown no signs of stress, so I am not too concerned as of now. But it looks like the branch separated a bit, it’s not loose and feels sturdy.

No worries

Just beefing up her arms to hold fat buds, pretty typical when you top them.

If it does start to tear away later from that massive bud it's going to be supporting just wrap it with some tape to keep it from breaking away.

Happy Growing

Not going to be a problem at all.
