not a good time to trim leaves fellow
as you want the plant to put all its energy into producing buds
the problem with trimming leaves is it really hard to get right, the hole ideal about trimming leaves and stems is to remove all the weaker shoots on a plant so the light can get do down the sides of the largest shoots, it reduces the plant need to stretching for the light as there no competition, by slowing the stretch down the shoots become thicker and stronger, so in flower you end up with lots of large thick buds
I try and aim for 2" -3" gap between each shoot and remove any leaves nodes that are more than 6" from the top of the main shoot as this has giving me the best results
a lot of growers get this wrong and it can take years to get it right, so my advice would be to try this after you have been topping and lst your plant and got it right for a few crops without any problems, them move on to this as it like pushing your plants to the max its high risk but a really high yield if you get it right
