RE: Applying TWP 100 stain

Have a few question about applying the TWP 100 stain

My wife and I turned over all the deck boards on our deck since one side had a solid peeling deck stain on it. This was a job. The boards were cleaned and a brightner applied and look great. Some of the board could not be used so new boards were put down. Should I skip these boards when we apply the TWP and do them after 4 months?

How long after cleaning and brightner can you wait to put the stain on?

I already did a small deck 200sg ft which also had some new boards added. I have stained these is this going to create a problem?
