Controversial subject

Hi all hey I'm looking for some input on a mater I have 2 royal flush and 1 blue lemon thai in pro soil,
400 w HPS going 12/12 3 weeks now, and I have some larger leaves that are blocking out light. Should I remove them or is it too late for that.

No, leave them be. They aren't blocking the light; they are using that light to produce energy (which it can store/share with other plant parts). Besides that a lot of the light is actually passing through the leaf, to be used be the lower leaves.

Try tying some back gently if it is that bushy.

Leaves = good
tiny little branches with tiny never going to be usable buds = bad

I'm talking the ones that aren't getting good light and instead are wasting energy reaching for light to feed an itty bitty worthless bud.

Thank you guys for the input I'll put this info to good use!
