Thanks for the detailed response. Yeah, I know I'm just getting started on training. I'm hoping this will be the fun part. Should be a challenge. I actually have an extra scrog net (one of the stretchy kind that attaches to the tent poles) that I COULD drop over the autoflowers. Any sense in doing that? Try to kinda scrog them a little bit?You have a ton more training to go...
I started my LST on week 3. I accidently topped her a week later while training and my journal notes say she showed signs of pre-flower 2 weeks later.
Since this is my first run I got scared and took off the training thinking she was flowering but realized she had a ton of time left so I resumed training until full flower 4 weeks later.
Bottom line; every plant is different but I would start training as soon as you can and keep it until you are in full flower. Remember, training is not a set it and forget it thing. You will need to check things often and make adjustments. The better job you do here, they better you final product will be later and pretty much what I attribute my plants shape to. I have yet to see any northern lights autos with my density but I may have just gotten lucky?
Not sure what you will end up but plan on aggressive training for the next 4-6 weeks. Once you feel like she is ready to start the flowering stretch, release all the ties but get some yoyo's and be ready to provide some additional support. With all the extra branches, she will need extra support for the fattening up period in late flower.
Going by my journal most of my training started at week 3 through week 5.
As for defoliation; I tried to tuck when possible and only defoliated when things got tight in terms of airflow or bud sites where obstructed.
Looking forward to watching your progress...
