Dont plan on flushing its a waste, me in abunch of other growers dont flush theres no need.. most who follow my journal doesnt flush read this thread follow the science not the hype..
A critical look at preharvest flushing
Buds do not take up nutrients. The plant uses the nutrients you give it to create the sugars that the buds use to bulk up and create the weight that you want at harvest. There is no logical reason to starve your plant just when it should be producing the biggest buds. It's the dry and the cure that create the smoothness and the taste that people think is created by flushing.
Now for 10 leafs till you get light penetration towards lower branches is not going to hurt at all.. autos dont mind defoliation just have to go slow with it... but if you like popcorn kernal size buds instead of golf ball size buds on lower branches then leave the leafs lol...but she will explode on her bottom canopy with about 20 leafs gone if it makes you fill better do 5 a day till you get to 20 leafs cut off in if not enough do 5 more mine loved defoliation and was thanking me for it... read the article i posted science doesnt lie..........
