Is this a mildew or fungus or residue or something else

So I’ve been chasing this problem that I have been back and forth trying different things to resolve and failing miserably. I’ve probably over complicated things again.
Reusing my medium with some fresh kryptonite (a local amended soil) and ewc and amended with only topdress amounts of Gaia green 444, 284, insect frass, mineralized phosphate and fossilized carbon. Top dressing half strength with the same and feeding half strength with biocanna stuff. Trying to get the best of both worlds but probably just making things too damn complicated. Have also fed with various teas and fulvics and humics and soluble seaweed (just st the beginning of flower and again week 4 or so).
Thought it was p/k def so fed a bit more, didn’t help; tried just h2o for a bit, didn’t help; looked at ph as a possible culprit - realized after 24hrs of aeration I’ve been giving em everything at 7 for the most part and the soluble seaweed being so high in k goes crazy high (like 7.5-8 range) and I might’ve done a soil soak without ph’ing first - so I totally could’ve raised soil ph beyond the range for p, but k shouldn’t be a problem. Have also looked at water temp when feeding which could be on the low end of optimal usually just a bit below 20°. Now I’ve noticed this disturbingly mildew like fuzz under some of the leaves in veg (need to check my flower tent) that make me wonder if I have something else happening. It could be residue from the pyrithium insecticide I’ve had to start using to combat a thrip invasion but am curious if anyone else has seen a similar issue on their grow.
Glad it is a weed and still able to produce some good flowers despite my inability to keep em perfectly happy (see last photo). Really appreciate any help you fine folks can offer!

additional info: 550w led; 3&5 gal fabric pots; don’t have a ph pen, but have tested soil runoff with the drops-going in at 6.5ish comes out at least 7; have been fighting fungus gnats for what feels like ever; avg temp/rh 22-24/50-55lights on/17-19/ ~55 in dark….. that’s all I can think of

I would say your throwing way too much stuff at it at once. Back off and just give some water for a little while. Don’t try to mix organics with synthetics sounds like it’s counter productive so pick one or the other and stick too it. You may have lockout from reusing old soil and not knowing what was left in the soil for nutrients. Try the water for a little bit and pluck those dead leafs they won’t recover then just pay attention to the new growth is probably your best bet. Hopefully some of the more experienced folks come along and can help ya out.

Fungus gnats may seem harmless, but their larvae eats away slowly at your roots. Shows up as deficiencies etc. I gave my bags of FFOF to my neighbor and picked up mother's earth coco and haven't looked back. People are obsessed with the latest trends which is currently organic and LEDs. Guess who also loves organics? Bugs. Just my useless opinion.

Sorry I should’ve been more clear: everything I’m using is omri certified - biocanna makes some pretty good liquid organic stuff. At least their boost seems pretty close to a fermented plant/fruit juice that I don’t have to make myself. I’ve also got some microbial mass in there (but ran out a bit ago) for extra soil life. But yes, you’re probably right - it would simplify things to just go one way or the other. I just read back in my notes for my first round (have kinda been going straight since then) and it seems like I went a bit heavier with the food and had no problems like im having now -except for some excess n issues with one plant out of the bunch - so I went and fed the newer ones in the flower tent a 1/2 dose of the 284 and 1/4 of the phosphate ….. guess will see what happens.

Bugs do love organics, but I have to disagree that they’re the latest trend - leds maybe ill give you - I’ll contend that it’s more like the og method. I’ve also been a big advocate for a good long time now, so I’m not jumping on a bandwagon or embracing a trend. I just don’t think man made nutes can stack up to Mother Nature.

The answer to your fungus gnat problem in organic soil is baking soda. You can dust top soil with it, or mix with water and make a spray out of it. 1 teaspoon per quart in a spray bottle can be used as a foliar spray as well. It can also help with powder mildew and mold in addition to killing pests.

Everyone's obsessed with having "organic". Bro im chem freeeeee! Right...some of the best fruits you've probably had were grown with synthetic and you don't even know it lol. It's all a mind game.

If you took a plop of chicken manure just as it was dropped, desiccated it and then analyzed it you would find the exact same elements and compounds in a bottle of “salts”. It’s gained nothing in the chickens gut to alter that.

someone mentioned baking soda sprays, you could also switch up to a citric acid spray. also nice VS thrips and PM

Thanks for that! I knew it was good for pm etc via making the surface too alkaline for it to grow, but didn’t know it was good for pests too. Considering the ph though and my concerns about soil ph already climbing too high I would be worried about using in the soil. Will have a go as a foliar though!

Ahh organics. He he. Its all salt farming and new medium every run. Not really using the tenets of organic agriculture. They just pick and choose inputs but not practice the methods. Maybe cannabis is not well suited to container grown culture with organic methods?? Inputs yes just salts and sprays. Growers with dedicated beds, that reuse their soil are doing more than other growers that get new soil regularly. If the first thing a grower does to fix a problem is go buy a spray for this or that, then they really don't understand organic agriculture when they started. If asked what the best amendment for soil for ANY issue and they dont mention compost (or organic matter) first they are just organic input salt farmers. The term organic now is more for marketing or virtue signalling. It does not mean the grower or farmer understands soil, ecosystems, IPM nor any long term strategies to achieve balance in their microclimate of inputs to yeilds.

Organic was and shall never be about bug free its about balance of bad and good. Bugs love organic but organic loves bugs its a relationship There is no difference between synthetic and organic nutes except synthetic is available immediately and organic relies on biology to make it available.
