Pruning

I would a little disagree with remove in them what I would do right now is top the plant let the 2 side you want to take of build another node top that let them grow past another node then top everything now you will make the plant wider than taller this way let it grow few weeks after that bloom it you will not even need scrub net etc and also you will have much bigger yield

big fan of removing bottom two axillary buds. like someonen else said, i wouldn't remove the single-blade leaves... until they are likely sucked down and just about shed by the plant on its own. Anything below a 90-degree bend should be removed, if you LST like that.

Yes

I ALWAYS remove those two lowest branches, they never amount to anything much. I usually remove the branches as soon as they are big enough to handle, but also try and to leave the leaves, but it is not essential. A razor blade makes removal simple.

I would wait another week, then cut them off. Let the plant get a little stronger grip, before stressing it.

If you are going to remove the lowest branches you may want to consider removing the branches but leaving the fan leaves. Since the plant is still small it needs all the leaves it can get to help with photosynthesis. I usually removey lowest branches once I have 3-4 sets.

Those shoots will most likely be hidden under the canopy so you can remove them for sure. If I were you, since this is a photoperiod I would remove everything at once, once time comes. maybe go for lollipopping or mainlining for a one time/rare high stress technique
