First of all, if you're fighting fungus gnats, there's a really REALLY simple solution and I GUARANTEE will work... get yourself some Mosquito Bits (Amazon has them or any plant/garden center)... follow the instructions about soaking the granules in water for 30 minutes, skim off the granules and then use that water for your water/feed... This solved my problem almost instantly but if you've got a bigger problem, you may need to do this once a week for 3 weeks... BUT. IT. WORKS.
I tried to look at your diary but it seems you've not kept it up so it's really hard to tell what's going on... so here are a couple of questions/suggestions:
1. Flush... Flush, flush, flush!! When in doubt, FLUSH! But be aware that if you're dealing with fungus gnats, this will only give them more steam - they love wet soil - just use the Mosquito Bits for your final gallon or two of flush and this will take care of them.
2. Have you ever checked your PH? Both input and run off? Checking the ph and making sure that both input and runoff is within acceptable levels is a must...
3. Your ladies are in flower... but your diary, since it's not up-to-date, does not say what you're feeding them. I am definitely leaning towards nitrogen toxicity - ladies in flower do not want loads of nitrogen... knock that back, give them only bloom nutes! Again, a really good flush will help this tremendously.
They are definitely crying for help - but I think everything is manageable... Get yourself the Mosquito Bits, do a really good ph'd flush, knock back on your nitrogen levels in the nutes and I think they'll reward you with all kinds of love....
Good luck!
