Yea, you want the stem to come out of the soil as straight as you can before you start your bend. I'd have waited more nodes but that's me and JMHO. The one that is going at an angle will stay like that. Nothing really wrong, more aesthetics, but the purpose of this technique is to force horizontal branches that develop more cola sites. These come off the main branch at a 90* angle . These can be trained to take advantage of openings attracting better light exposure. One still needs the main branch, the vertical trunk-line, supply line. Say a trained branch is 6-8 nodes long and is now horizontal. Each node will grow a cola straight up. Hopefully, there's no branches above this and all those colas get great light, get juicy and please master...
