Bloom defol. How much and where??

i'd avoid overlapping leaves... this causes standing water and a foothold for pathogens. leave as much as possible... leaves power growth. no way aound that. less = less energy abosrbed... removing shielded leaves is less of a negative than removing leaves at top. some penetration might be good (no certainty here with little to now research involving suitalbe sample and comparing to a control). But, remembe inverse square law means distance from light significantly impacts intensity and quickly... 2x the distance = 1/4th the intensity. You lights and envionment will be a factor too... this will impact how deep you canopy will grow good bud... experience from previous grows helps pick out a horizontal line where you want growth and to remove anything below (unless heavily into extracts and edibles, this larfy shit at bottom isn't too useful.. if you have a use, there's a reason to keep it -- oveall yield will be beter but with larger proportion of larf ... a lot of these things come down to personal preference too) some LST might help too, but becareful with woody stems.. they will snap. but, spread out plant a bit if you can... bending may not be enough. some bamboo sticks or similar can be used to spead things out and avoid the natual tendency of plant to gow back in shape it was before (toward light). So, just make sue air flows through the plant well and don't decimate you canopy... shouldn't have a bunch of light hitting the floor, for example.. that's wasted light.
