i've been fighting em too the past few months. i spray my veg plants with soap+oil+essential+hydrogenperoxide try cinnamon oil and rosemary and peppermint together with the standard teaspoon of soap and teaspoon of vegetable oil mixture you would make as a leaf wash. i add hydrogen peroxide because of its effect on living cells. i assume maybe it'll help kill the adults. since the larvae live on leaves i tried bti water (mosquito dunk) mixed into the water when im not using the hydrogen which i assume would kill the bacteria. but between that spraying all my plants in veg as near to daily as i could manage... definitely gonna have to get a 3 day streak going to start seeing any benefit, same as with spidermites... the colder weather cooling down the space, aggresive leaf removal and spraying the top of the soil also. i think i've beat them out of my grow area. theyre still present somewhere near my houseplants which dont seem to get effected in other parts of the house. but if i put a seedling or seomthing under the same light as my houseplants ill start seeing the telltale signs.
That stuff works good, I use it as a spray and drench.
Mate I've just gone through a my 3rd plant in last 6 months. 2 were recent. They literally went from thriving in wk 1 to 3 to wilted leaf and died within 24 hrs. And it was same started in older leaf clawing but looked like phos before they started to claw. I was in soil that has been going for a year bit longer. But had start of real heat here. I'm sure it was root aphid or fungus knats. No gnats flying around had em before. I think my situation was over watering In a medium with heavy organic matter. Which depleted oxygen and the bad guys came out to play. This first time I've dealt with this as only gone to xl containers for a better living system. I'm in process of moving back to smaller containers unless your using a bed indoors with a nice dripper system I don't think it makes life any easier to have larger pots. Maybe if u have microscope and can be sure on your biology. Love your post. Cheers
Yeah I'm leaning towards that. I've been using less casting and it's been a while since I've added any sort of aeration so it was staying to wet and getting the wrong critters due to still being some worms but as I don't add aeration. (Mainly I've noticed I've been over watering trying to do small watering but have been heavy handed.. transfered to smaller bots and a coco soil castings with I like to use many rock dust fulvic, amino, seaweed, gypsom potash and (phosphate, bld n bone and magnesium if needed) and fpjs aloe, Mexican marigold, canna are the main ones in use. I literally just just my first worm tea brew deadpan heads mix. Glacial (i used volcanic) rock dust, worm casting(orcompost) molasses (I used a fpj mad with aloe) fulvic acid, and seaweed and bubbled for 24hrs due to warm temps. I've got good sighns at moment. I've got we 5,3,1 in flower was the issue I didn't have it in veg.
