Wow...this is the argument that never ends.... So here's my fence riding position.... I remove any leaf bigger than my middle finger during veg......It's about controlling growth. It makes short , close noded plants....with a healthy root system. It's an adaptation of bonsai techniques. Bound roots and proper pruning create minature copies, which is what sog with clones is all about, As soon as they move to bloom I quit taking leaves and let them bud.....removing lower, nonproductive growth... I guess I'm gonna have to try going a few weeks into bloom to see if it decreases stretch without reducing yield.....but I have a very consistent perpetual going, so I'll just have to get a bug and do it on a few plants out of a batch. Only problem then is the ones without the leaves removed would block the ones with them removed, cheating the outcome........don't like to experiment with full batches..... I love to tinker but I've gotten very lazy and methodical..
Remove if you want to I say.......but a few at a time, not all at once.......to be sure....
