Purple lemonade by fast buds

Hi again!, Beginning of week 5 they are bouncing back nicely from additional training from this point on I will just let it grow........but I am afraid I was to late in the initial training I waited to long to pinch I thought it was 5 nodes but ended up being 6 and in theory it should produce more bud sites by slowing down the middle growth it causes the lower nodes to pop and rise up so by the time it reaches the top the middle has recovered and rejoins the rest of the grow resulting in a more even grow and more buds but sadly I see today pre-flowers on all 3 plants ..... pre-flower at this stage right after a training event is not good recovery will cause this plant to be shorter than normal slowing growth - stretching slows all buds could develop close to one another a.d cause different issues but only time will tell .... always love growing autos.
