If the first batch of nuts had no root yet, they may have taken a little time to wake up. This can delay growth.
It can also lower the success rate, as sometimes the scion dies before the nut is ready to make callous.
Sometimes it’s fine. it will be interesting to see if there is any practical difference between the first and second batch of nuts, given the roots were out on the second ones. I have never worked with seguinii, so that wil be fun to see how it works out too.
