First time blackberry gum auto outdoor

This week I repotted two of my three plants into 10l pots (2.6 gallon). I cut out the bottom of the pot and just placed the smaller pot in the larger one trying to stress the plant as least as possible. The move seems to not have stressed the plant too much and looks healthy. I wanted to start giving it nutrients right after the move but my nutrients ordered online are facing a small delay. Starting tomorrow they shall also get an extra boost of organic matter, potassium and nitrogen. Flowering has begun this week with the first pistils appearing on the top of the plant. The plant seems healthy and is starting to grow side branches. Hopefully it keeps growing well the upcoming weeks. The weather has been terrible with lots of rain and little sunshine so hopefully this upcoming week is better.
