your way too far to be using milk and when you do forget about the misleading information on the net and use full strength homogeneous milk but it’ll only work with the bright outdoor sun or with lights like 1000 watt metal halide or high pressure sodium..
your only real option is spraying them with
hydrogen peroxide around a 7% strength.. hopefully somewhere close too the room is the shower, put the plants in there, cover your soil and spray SOAK each one everywhere, let sit for 15 mins before putting back in room,
than every couple days just spray the plants in the room till finish,, also spray everything in that room..
at harvest cut each branch off, have two huge tubs one filled with a 10% strength peroxide and the other with clean water as you’ll have to wash those branches, than let dry off to what they were before washing to hang dry or whatever method..
than i’d only maybe make hashish, but i’d for sure make a hash oil with 99.9% isopropyl., as i just did this with a wild thailand outdoor plant that was on deaths door from mildew etc.. done pics below of what i got out of her and honestly it was great smoke and i still have some thai hash oil left..
some pics of hash/oil twice, but this was pretty much all i got from a badly infested wild thailand plant..
smoked beautifully!!
