Leaves Yellowing & Drooping! Fungus Knats

Please Help - Have a problem with my Orange Sherbert Auto - Sub-Cool soil Homemade, 30 qt ProPot - transplanted 2 weeks ago - roots are white and have a ton of damn Fungus Knats & been using Neem & Insecticidal Soap spray with Mosquito Dunks 1/4 in gallon of water every other watering! Don’t know if it’s Sulfur deficient?

Stop the Neem oil and soap. Just use the Dunks or get some Microbe-Lift BMC. Could be the soap and shit messing shit up, or the soil is still cooking.

Did this happen after transplanting to the Sub Cool Mix? Oh and wear a mask or at least try not to breathe when you're messing with dusty top dressing.

Yes it happened after transplant, but doesn’t look like roots have made it to the Sub-Cool yet, since it’s only bottom 3rd of bag. And original 1 qt pot soil is just regular organic soil. But is only plant out of 5 to have this! All have the damn Phats.. little bastards! LOL - tried to hold off replanting as long as possible, but they where getting stretch in my 3x3 grow room. Weather has been crap here in Washington! I’ll see if Home Depot has the Microbe-Lift! TY

I'm not sure but it looks like your auto maybe have started pre flowering? Can stress trigger an auto into flower prematurely?

Never had it happen before, they are usually shocked for a couple of weeks, but always come out fast & furious! My other 4 look good & started kicking in about 4 days ago. My concern is the leaves are starting to cup & fold under at tip? Going to start hitting them with Advanced Nuit’s Sensi Bloom ph Perfect, Big Bud at 1/4 dose till the roots get to the Sub-Cool. First time I have used the soil.

Had good success in compost that I made last year with Hindu Kush Auto

Id suggest covering the soil also or it will be a constant

One thing that worked well for me with gnats was the use of an automatic watering system. The system I use has 3 inch spikes that go into the soil. This allows the water to get into the soil without getting the soil surface wet. Drier soil surface can help with larva gnats a lot. I just give the soil surface a little spray of water so it does not dry out and get nasty. And don't forget the yellow sticky pads and if things keep getting worse you can use a product called Gnatrol.

What's the soil volume?
How much do you water and how often?

30 quart cloth ProPot - haven’t really had to water, they are outside and has been raining most of the time. Watered once last week with a quart of H2O with Mosquito Dunk for each plant, just to get stuff in the soil! Too, wet for yellow sticky cards & don’t have room in my grow room to wait out weather for 5 of those pot.. sprayed soil and plants (top to bottom) yesterday with Neem & Insect Soap. Worried more about what the leaves are doing! (Only on 1 plant)
