Start Flower...defoliation for Northern Light?

Just the bottom ones that don't get any light (account for future growth that will cover up even more the bottom leaves) and if you can by removing just 1 leaf manage to get light penetration into the whole central part of the plant (where the buds are at), that would be a good one aswell (check my Sweet Gelatto number 2), and its said that by removing just a few healty leaves at the very beggining of flower, the plant starts to spend even more energy into bud production and doesn't produce as many leaves redirecting that effort into fatter buds. (Check my haze outdoors, only producing bud and just a tiny bit of folliage, got 4 stems growing filling with bud and very little leaves). Good luck growmie, defoliate safelly, don't overdo it.
