Problem here or perfectly normal?

So I’m 6.5 weeks into flower and I know to expect larger fan leaves to be dying off, but I want to get some opinions on these and make sure it’s not something I’m missing.

SF1000 3x3x6, 2 plants in 10 gal fabric pots.
1 plant in FFOF, 1 plant in a mix of FFOF & FFHF (water, feed, water, feed)
Normally giving 2 gal per plant per feeding, when feeding 3/4 tsp Beastie Bloomz per gal. I noticed a few fungus gnats so I held off watering for almost a week and only gave 1 gal per plant. I have a ton of airflow in my tent and have only seen the gnats low to the floor, so not sure how detrimental they are at this point.
Temp & RH pretty steady 78~83° & 41~53%
Last time I checked my EC was 1.3 going in, didn’t get the chance to check runoff though
So are these leaves dying off perfectly normal, or a sign of something else?

I have fungus gnat issues as well so i have to bottom feed. The top inch or so of each pot is perlite and DE( i grow organically). I have never done the neem thing because its a wasted feeding. Theres also a hydrogen peroxide method HOWEVER:

i think you have nitrogen toxicity. The leaves are super dark and “clawing” which is a telltale sign…

I’m only using a 0-50-30 at the moment, should I just give water the next few feedings and then resume with nutes?

Super green leaves with a claw is too much N. I would do a flush and cut back on nutes..
Spinosad soil spray works great for fungus gnats..

I’ve only been using a 0-50-30 for the past few weeks when feeding, but I’ll just give plain water for the next few.
Is the fungus gnat issue something that really needs to be dealt with at this point if it’s not a crazy infestation?
I know it can lower yields in flower, but my plants are underpowered as it is with only 1 SF1000 so I’m not super worried on that end. I was more worried about em getting stuck in the buds, but I have 5 fans set up inside, with 2 6” clip fans for intake, so a total of 7 fans, which is why I think I haven’t seen any actually flying.
Would you still treat/spray at this point?

A few gnats can become an infestation in no time..
You only need to spray the top of the soil where the larvae hatch..
Get them now or get more later.. Short life span but a lot of eggs!

K, I’ll place an order, thanks. Aside from the fungus gnats, do those fan leaves look like they are just dying with age or from a problem?

Do you have a brand you’ve used or can recommend, doing a quick search turned up a bunch of different products. Is food grade DE enough to do the job?

If you use a layer of perlite then de on top and keep it dry. Otherwise ie heard of removing the top inch or so of soil and using A LOT of food grade de to replace the top layer. After that, you would likely have to bottom feed. The fungus gnats are bad. They kill seedings so if you start plants during your flowering cycle in another room they will find them.
the other problem with them is that they die and get stuck in resin glands. I like my buds to be perfect so i dont want to find little flies in there.
Depending on the level of infestation they are already in your buds…if your leaves were lighter, you would probably see them.
as we speak i need to go put perlite and DE on a plant because i refuse to bottom feed it. I will probably pay the price for that hour or so of time where the soil was bare.

Placed my order for Monterey’s spinosad earlier tonight so hopefully should be better dealt with soon. Having flies stuck in my buds is my biggest concern. I’m sure I could limp to harvest with the potential root damage, but I don’t want to smoke flies.
I have 5 fans set up inside my tent, not counting 2 intake fans, I can only hope it helped keep them really low in the tent

Monteray Spinosad... DE is only effective until it gets wet, never worked for me!

One last follow up if you don’t mind.
I have the Monterey’s arriving tomorrow, my girls are thirsty, do you know if the Monterey’s is something better applied to dry or wet soil.
I imagine directions may be on the bottle, but preparing myself in case they aren’t lol

they will be. i'd guess it will work better on wet soil, but it's pretty systemic, as long as it touches the plant, it will get absorbed to where it's needed

So here’s a follow up report, with a follow up question.
Just did my first application of Monterey’s yesterday, 24 hours ago, along with placing this yellow sticky pad.
I haven’t caught a single fly on the pad in the 24 hours since setting up. If I had a case of fungus gnats, shouldn’t I have caught some by now on the pad?
Would you recommend another round of the Monterey’s seeing how the situation is right now?
Thanks all

i would think you would have trapped at least one if there were enough of them to be a problem.
i think i would wait and see if it starts to occur again, if it seems to stay good, skip it, if not, then i'd go two more rounds, 3 days apart
