Please help! :o

I know h202 works for the gnats but I'm afraid it will kill the mycorrhizae.
Does anyone have experience with a neem root drench?
Or perhaps citric acid, idk what works best.
Hypochloric acid I sadly can't get around here

I use 1 oz spinosad to 1 gallon water as a root drench and change to Permethrin 36.8 if that doesn't work (different dosing and the spinosad usually works). I run sterile since I'm in hydro. What do you need microbes for in hydro? The plants need the food directly. Microbes in soil make the food available for a plant eventually but even in soil if you have to rescue you go with immediately available nutrients and not wait for your herd. They are two very different concepts of growing and I have stayed in my lane so maybe someone who is a better grower and with far more experience will be along to help.

Have you spoken with the guy who recommends this? Can he help you?

How much would you allow coco to dryback before the next watering?
You never have algae forming or any issues with not having enough oxygen in the rootzone if you keep it moist at all times?

I've learned 3 months on a 120 light grow in phuket, now I started this own grow and sadly don't have direct contact with the guy who taught me

Mycorrhizae help also to protect against botritis, pythium and other nasties

This was the result of the dryback and then saturation with 20% run off

As a new grower, let go of preconceived ideas and embrace what experienced growers are saying, often “what we’ve learned” is misinterpreted through inexperience and a nuance to be applied after the fundamentals are sound. Just my opinion/experience. The more I’ve forgotten and listened, the better gardener I’ve become. Don’t over stress about things, they look good for now. failures and mistakes are inevitable and unavoidable but valuable learning opportunities. Keep up the good work. Also, don’t underestimate the gnats and address it right away, IPM is also a valuable part of things, and keep your pens calibrated.lol.

You don't, you water while it's still wet. I know you don't wish to hear it but if you would like to grow in soil move to soil. Drying back hurts you in coco. Especially if you don't have perfectly buffered coco

Look into sf nematodes for your fungus gnats. Sometimes they can cause problems which cause phantom deficiencies.

I'm going to try to water them to fill capacity every day then.
Still moist or not, I'll keep you updated on the difference it makes.

That's the problem since you mixed coco with dry nutrients every time you water you feed and possibly too heavily but your coco would prefer moisture. You can't treat amended coco like regular coco. So I don't recommend doing that with your coco. I honestly do not know what to do in your situation but change substrate. Have you tried communicating with the guy who suggested this?

Not really following you, what dry nutrients have i added?

This is much appreciated however any beneficial bug is super hard to come by near me. No companies dedicated to it and importing is a hell

Sorry, I conflated you with someone who added Gaia Green to their coco. Just in coco, watering daily and keeping her moist and I think you'll be much happier. I'd love to see the results from that.

 

[kushdoctorWolf]

No worries, you got any idea what causes tearing in leaves and this weird spot;

The first white/pale spot looks like something was eating your leaf. The second image shows a tear that looks mechanical but the black spots don't. I don't have much experience with bugs. I've been pretty lucky. I'm sure someone will be along with an idea but take a very close look at her to see if you can find a pest, also for the source of mechanical damage.

the most simple and effective treatment ive seen for fungus gnats is liquid BTI. very simple to dose out, no straining out bits although the mosquito bits worked for me too. get some sticky traps, I like to keep blue and yellow around and deployed.

Although i have never grown in coco, as i understand it, it likes and needs to stay damp.

 

[ALPHA.GanjaGuy]

imo the easiest and fastest way to control fungus gnats is cinnamon, turn fans off, sprinkle on top, scratch in, sprinkle a little more on top, water litely and turn fans back on.

Cinnamon kills larvae/hatchlings and prevents adults from landing to lay more eggs.

You can also make a drench with cinnamon, soap and water but I have never tried or needed to do this. Typically doing the above solves the problem in 1-3 applications, applying 2-3 times a week. You can/should also already have yellow traps.

Bonus, your roots will love it too!

Much appreciated!! Really solid advice y'all.
I've tried to inspect and don't see any signs of pests, it was what came to mind as a saw the hole in the leaf ( i only have a x30 magnifier.. x100 has been ordered and is on the way )
Meanwhile the ladies look pretty good and havnt curled/taco'd more than they did before.
Also havnt seen a single gnat for at least 3 days now but I know the fuckers can be sneaky and maybe they laid eggs and I've got plenty of pupa in the rootzone.
I'm also afraid I might even encounter new pests here in thailand unknown to cannabis growers before.
But all and all were going forward, about to treat these phantom gnats with a root drench and I'd like to try the cinnamon and will do a preventive foliar spray with some neem and propolis tonight.

Anyone experience in applying the 2 together?
( propolis and neem )

I don't spray Neem as I've had friends whose grows were wrecked by using it. You're not in flower and like I said I don't have much experience so you're on your own there.

How are your plants looking with you keeping them moist? As for the bugs in Thailand that's where thai sticks come from so I imagine your genetics will make it Oh for some of the sativa seeds from there in the '70s. I had a friend who was stationed at Udorn in Udon, great memories.

 

[kushdoctorWolf]

Did a test on one plant last night, didn't suffer from the IPM I made so ill be applying it to the whole herd next, never spray anything in flower. Unless there's an ongoing infestation I'd do it up until the first week of flower but after that you have you have to find other methods.
I've been keeping them slightly moist but still holding on the the dry/wet cycle with plenty run off.
They're growing a lot better now I'll post some pics later.

Just a question the PH in my run off is quite a bit higher, goes in at 5.9 came out at 7.
Is it because nutrients are being uptaken and it alkalizes the whole bunch?
