im very green to this, does anyone think I should ...

Your best bet is to try and space the lights evenly around the tent to make sure your light coverage is as even as it can be and minimize spots with less light coverage. You don't need a par meter to see if a part of your plant is in the shade. I would also do some low-stress training for sure. Bend the tallest branches down so that they are the same height as the shorter ones. That will allow more even lighting of the buds and also help prevent the shade spots that can happen from tall branches. Be careful with the LST as going too aggressively can cause you to snap some branches. I would bend until just before you think it will snap and just leave it there. Maybe try again the next day and see if you can move it further. LST is a bit tricky once you've begun flowering as the plant tries to stiffen its stems to support the flowers. You should also do some decently heavy defoliation. around week 2-3 of flower, I usually strip the lower 1/3rd of the plant thats not receiving much light as those buds won't develop into much. After that, I clear out a lot of the fan leaves through the rest of the plant to open it up for light to reach lower buds and allow more air to flow through the plant to prevent mold. Don't go toooo crazy and remove all the leaves though. I will usually take off 25-30% of the fan leaves evenly across the plant making sure to specifically go after big leaves that are blocking light from lower buds. Good luck with the grow and I hope you have a good harvest!
