I usually wait until I’ve got 2 or 3 nodes so that I know which direction to bend her to get the best use of light. She’s still really fragile this early on. She does however look pretty healthy.
Check out my OG Diesel Kush autoflower diary. I started heavy LST at 10 days old. It came out fantastic and is still growing. It's just about to start actually budding soon
I would wait at least a couple of notes but that's my opinion. They say do it as early as possible but everybody has there own preference . Just try and if don't feel right adjust . Happy growings mate 🤘🏻🤘🏻
