My view on foliage cutting is:
Does the leaf I'm about to cut hinder the plant more if I don't cut it.
Being still very early in the plants life, every leaf that gets light is a solar panel that will increase the energy your plant needs to grow. If the leaves you cut did show signs of being a problem that would spread to the rest of the plant or if it looked to sick to synthesize light relative to it's usefulness as a solar panel, then you did a good thing. But if the leaves simply looked "off" persay, then that is when you refer to the rule above.
As an example during week 3 of veg from seed, the lowest leaves (bottom most prominent fan leaves) of my white rhino had what looked like rust spots on them. They were few and overall I let it go as it looked centralized to those leaves only. Now 2 weeks left till harvest, those same leaves are even bigger and have taken in a lot of light = energy for my plant as a whole long term.
Another example of prudent trimming is when your plant is very bushy an could use a few less leaves (try not to cut the big fan leafs) for better air circulation. Also a lower bud branch below the leaf your cutting, could as a whole, use the light more then the one leaf above it (use practical judgment). Also sometimes as the plant matures in week 4-5, trimming some of the bottom most bud points that are the lowest, most shaded, runt etc etc, will allow more of the nutrients an energy to go topside to the typically higher producing nodes.
Cutting those leaves imo will not hurt the plant but might have reduced long term overall energy intake.
Hope that helps and wasn't to much info.
