the good thing is they are appearing now and not earlier,
they dont ahve much time to damage the plant, but for your next grow you have to be aware
tht they come back
start your new grow in a cleaned envoirement,
and start with preators ( google helps=)
because if they damage ayoug plant, you can throw them away
you can reduce them mechanic with vaccumumextractor or washing with a sponge,
you can flueh them away under the shower, do everythogn to minimize
