alright im gonna start off by first explain wtf it is that's going on if u got rood aphids , first off i want you to look at ur girls , have u had a sudden or phantom deficiencies? it will most likely look like manganese or a magnesium deficient.notice the leaves yellowing and feeling ruff almost like ph is off i have ran into the exact situation u are having and all i can tell you is that you are waging war on the hardest to kill pest with growing. ive only herd of defeating these things in dwc. ive personally used sns 203 and killed 90% of these bastards. the problem with these little bastards is they will climb up the stems so use Vaseline (petroleum jelly) and smear it all around the stem when u drench ull catch alot of em and if using plastic pot around the rim, and glob the openings where it drains these bastards run off and in defense mode can even lay a cocoon and go dormant until winter. and then bam just like that there back. now if $ is the issue like it was mine u can keep using sns 203 every 6 days to try to keep killing them!also used pyrethim bombs as well. i managed to keep them under control for a few harvest while i started new genetics in a tent or had a buddy veg a few out for me so i could go straight to flower with little down time having to veg myself.,while I SHUT DOWN AFTER LAST HARVEST, i did not shut down for long, i shut down long enough to seal off the intakes with bugs shields as i did not do when i first started 4 years back, ive never had a problem with this pest until now..so like i said i shut down and trashed bleached and cleaned every nook and cranny. and keep good hygiene before entering Ur room. i know u already know this but this also means discipline on where you get ur cuts from. some ppl have root aphids and don't even know there passing them, they think dunking in simple neem will kill everything, well not these hard shell root aphids. they start off small and white, then as the grow/mutate they change colors often yellowish green/black/even pink depending on there diet and once they've colonized and can no longer all live in you soil they grow wings and then there in your sweet sweet buds layin live birth in the leaves then. like i said it sucks that Ur going through this don't feel alone in this battle there's not to much info on how to successfully kill these bastards. i myself had to learn the hard way. and shutting down for a few days AFTER HARVEST LOL, is the best option to fully eradicate these pest......if u need or would like anymore info feel free to ask!!! good luck and hope this helps!!!
