they will come back , try not to cut any leaves in flowering , removing them mechanically is the safest way ( for ur health ) go find a sprayer and spray from close distance so th pressure makes them drop off the leaves , if u do it like daily maintentance u want give them the chance to multiply in great numbers , low temps + high humidity + great air cyrculation = natural control
20c and less , 2 times per day spraying ( one on the first hours of daylight and another on the midle ) , 1 extra fan making the stems swing a bit more ( not like they strucked by huricane ) = ftw
u can easily remove all the webs with spraying from close distance without affecting in any way ur plant / buds , thats what i do if i havent spoted them on veg where i nuke them straight on the plant , on flowering tho i keep in mind that what ever i spray will eventually get to my lungs
