I'm not going to read all your posts, so here's what I have to say, hope it helps;
First of ALL. Never ever ever cut off a healthy leaf.
If you want to encourage stimulated growth, or direct hormones to particular branches, the most efficient way is to cut lower branches as soon as they appear.
At each node, first a Leaf emerges, then a Branch, and finally a Flower.
When the Branch appears as two little baby leaves, just pull the whole thing off or chop it off.
But leave all the leaves, these are the solar panels of your plant.
If a leaf dies, or it's almost dead, remove it at the trunk.
This means completely removing the petiole (leaf stem) so it can't rot away and colonize bacteria that will invade your plant.
I noticed in the first picture I clicked on, that there's two FAT petioles sticking out, chop those bastards off, it will stop the plant from feeding the "leaves" that died.
They look really really good, but very very skinny. I'm assuming you chopped off the large fan leaves? Don't do that next time. Even if they block light to lower nodes, they will feed those nodes by collecting light.
If you need to encourage the branches to reach the canopy, provide them with adequate light, and care.
Good job though, they don't look like the haircut affected them too badly.
Good luck!
Oh in those last pictures, I noticed a seedling to the right, give him his own bulb.
One little 13w is plenty for the first week or two.
If you are doing LST, you can use lighting angles to encourage the plant to follow the path of your lst. Will cut down some tying time if you know how to do it.
Again, good luck, looking good, and you clearly know where to find answers to your questions.
Most of all: ENJOY!
