Hello fairly new to this site and fresh back into the grow so go easy on me, I have a problem with my baby! I have discovered a fungus gnat problem and have been trying to combat for maybe 5 weeks now (problem still consists so resulting to neem oil) but I would like to know if this problem is connected or if I have a fert burn or a deficiency. To kill the fungus gnat I have reduced feed to let the soil dry. (All equipment etc has been use in previous grows with no problems.) Tia.
It could be a bug?

That first pic would lead me to think bugs. Grab a scope, or even the zoom on your phone may be good enough, and check out the under side of that leaf. The neem should help clear that. The second pic is showing some nute burn but it is not to what I consider lockout that would be pic 3 imo. She has locked out and is feeding on herself to keep her flowers going. again, just an opinion

Yes I've checked the under leaf, do you know what to look for specifically in this case?
Could you give me more info on lockout? How to prevent and/or cure?
Thank you!
I'm looking into this now. Thank you.
It is coco
I did think I should try this, with trying to fight the fungus gnat I've reduced feed for longer than I would of liked and did think it was possibly start of maybe more than one problem? Hopefully this can be saved.

Well simple fix then. Gnats just add h202 to your feed. They’ll be gone. The way your feeding is your problem. You need runoff with at least every other watering. Never straight water. Keep your mix low around 1 EC with added calmag. So you need to have your pots elevated so you can collect the runoff without moving the plants. Don’t let your pots sit in the runoff water.
Simple fix. Mix up some nutes with calmag and feed them. Get a lot of runoff. This will flush out your build up and feed at same time.

You got sticky traps in the pots to catch as many adult gnats as soon as they emerge? The adults don't affect the leaves but thrips and mites sure do. See if you can get a product called Gnatrol and water that in. It's a bacteria to kill the larvae and one dose wiped mine out. Neem doesn't seem to do shit.
Good luck!
Good luck!

Hydrogen peroxide and you'll want the 35% food grade stuff at hydro or health food stores and some garden centres.
I let mine sit for a half hour in runoff then remove any left over. A small towel works great for getting the water out. I just wring it out into an old plant pan and let it evaporate in there to help keep the RH up.

Yikes. You need to educate your self my friend on growing in coco. There’s plenty of info on it.
my our problem is you think it’s soil. It’s not it hydroponics. Treat it as such.
Ive given you all the info you need. Do some reading. It will help you 10 fold. Good luck.

You let your plant drink the runoff? You feed to runoff to get rid of the old nutes.Why for you do this? coco remember.Hydrogen peroxide and you'll want the 35% food grade stuff at hydro or health food stores and some garden centres.

I'm not using coco and didn't factor that in. I can't see why anyone would want to use coco as it's so much more hassle than a peat-based media like the Promix HP I've been using for 20 years. Actually Sunshine mix #4 with added perlite for the first 7 years then Promix showed up here in northern Alberta and I've loved it since when I'm not doing DWC.
Soak it good, let it dry out then soak it again. 3 - 5 days between waterings. Easy-peasy.
Was trying to educate myself, its why I'm here, 1000 different ways to grow and 1000s of crap info, ive read shit info (thats why I'm here). I will make mistakes and learn but telling someone to just read doesnt help, thank you though.
I've been planning changing from coco as its a faf, ill look into promix hp and thanks for your inputI'm not using coco and didn't factor that in.
