The problem (as seen in the image below) is that on grow my custom tree the bottom block, where previously was the sapling, has a chance (i think), of appear rotated.

Thanks for helping 

The only problem I can think of is that you notify nearby blocks. The logs probably rotate accordingly.

What do you mean?

And how can i fix it?

 

Can someone help me please!? 

When I did my copy/paste mod, I had some blocks where they cared how they were placed and it changed the orientation such as droppers/hoppers.  I had to come back 1 tick later and set their meta data or they wouldn't obey the orientation I desired.

 

I just looked at the blockwood class and I do not see any evidence of that issue here.  It has to be how you are placing the block.

 

 

Is there any difference when the tree grows from worldgen versus you grow the block with the bonemeal in your hand?

Yes, the trees from worldgen has no rotated logs (at least the ones i saw) and the treen grew by bonemeal, have a chance of generate with the bottom log rotated.
