1 gallon water-1 tbs baking soda works fairly well on tomatoes. My neighbor told be about it. He also said the blight lives in the soil. Using mulch prevents the soil from splashing on the leaves when it rains.

Uggh, not in my experience, baking soda is BS in my book, I went straight to copper, probably not advisable for cannabis though, H2O2?

Does anyone know what this is? I caught leaf septoria on the last run and now this one is showing signs of the same thing. Any ideas on how to rid myself of this I'm scared my baby is gonna get really sick

I don't know what that is right now but I know what it's not; it's not leaf septoria and I don't believe it's any type of a fungus or bacteria, most likely related to your malfunctioning pH meter

Liquid copper fungicide is the best, I use it whenever I need it, agree about baking soda being no bueno

Keys to happy healthy seedlings.

Water 24 hrs thoroughly before putting the seeds in. Should not have to water for a week or more if humidity is good. I like the idea of weights before and after.

Humidity of 60-70% (50-60% is ok) will ease the stress. But it's important to keep indirect airflow accoss the top of the soil. You can't do that if your cups are half full and the seedling is halfway down the cup creating a stagnant air pocket.

Temps of 75-85f work well 80 is nice.

Root zone temps of 70-73f are ideal.

Don't use a dome for seeds only clones.

Don't give any nutrients.

Not hard rules but goals to aim for.

What the leaf temps is the key, you can have heat stress in moderate temps. Added with low RH creating respiration issues. Sick plants can contract all sorts of fungal, bacterial infectious or pests.

What type of light and how close is it?

Kinda feeling like RH is to low, light is to close and fans are possibly direct airflow and to close?

So the light is a mars hydro tsw2000 it is turned all the way down at the moment and is more than 18 inches away the fan isnt point directly at them either.

The craziest part to me is that it only happens in this tent. I use a lumens meter to make sure the lumens arent over 1000k. I have also even tried neem oil on it but no luck.

I think I got it now. But I'm having trouble with the plant in my flower tent. It's like any time I out a plant in there it starts acting crazy and catches this fungus.

Just want to add, there are two stages, germination and seedling. For germination, my greatest success is 5:1 soil to water and seal the container so warmth increases humidity. As soon as the seed pops and the seedling stage starts,

open it to air and wait at least a full week to water. I will never understand starting a seed in anything larger than a solo cup.

Have you thoroughly cleaned it?

I'm going to start in about a week in jiffy pods, figured I would pre hydrate them at the time of the seed soak to let them dry out a bit, I assumed it would be best to use the little 12 cell dome (starting 6 plants) as they dry out really quick, will be up potting to 5 gal sacks when established.

I would advise no dome with seeds they start off with a root system unlike clones. Unless your humidity is under 40% then it may help a bit.

I use jiffy pellets as well. 7-10 days they are good to go as soon as you see root transplant. There is some feel to how wet to get them and the directions are pretty close. If not as you say soak em and let em sit a day before using.

I'm a paranoid grower so I microwave mine for 30-45 sec to ensure any eggs are destroyed. If they get a bit to dry which will happen I pick em up and mist the sides with a spray bottle. The key is damp not wet.
