okay...u should be okay identifing them this early...
u need to go get some neem oil asap.. u need to use it in veg be4 flowering to prevent this type of situaiton..but u can use it toward the 4th week of budding and then stop..feed it to ur plants with nutes..every few days when u mix ur nutes..1 teaspoon per gallon..wait till ur lights are off, and mix this neem oil up in2 a spray bottle, lesss than a teaspoon per bottle..wait for lights to go out..work by a shop light or latern u bring in.. take each plant out and spray the living shit out of it with the neem and water..pay attention closley to bottom fan leaves, the more affected 1's, and spray the underside..if u have a cloth, wipe each leaf down..dont miss anything..after pulling each plant out and spraying it down..put them all back in place..the next day come back at them with plain water, via ur spray bottle..continue spraying water and every 4th day spray neem and water. do this for 2 weeks, getting 3 doses of neem spray on them every 4days. during the water onlly spray days, u can combine ur water, with disinfectant soap..to make a soapy mix which helps knock them down and suffocate them..as long as its mild hand washing soap with no fragrances it wont harm a thing..continue feeding them the neem with ur nutes every few days until 4th week of flower..its actually benificial, and it helps when pesky critter bite the leaves , they get neem oil in there system and cannot reproduce. mites come in wavs because of super fast breeding..the neem 2 week treatment, will surely get all succeeding waves.. also work on getting ur temps down to 70's ..they hate this..and cannot reproduce anywhere as quick..if u have a/c blast them bastards down into the 50's and 60's when lights go out..also u can hang a hot shot pest strip found at lowes in the room..if none of this helps then ur going to have to buy 3 dr doom 3oz foggers..pyriuthum bombs, and bomb 3 times at 4 day intervals..u can do this all the way to harvest almost so theres hope
