Virus? Fungus? Weird seedlings! What's going on here?

[kumar]

Dear Ladies and Gentleman!
I had a problem few weeks back with my seedlings. They all looked sick (a lot) so I throwed them out and sanitized the whole growroom. I used ozone generator and bleach to clean everything. Plus I bought new growing media (peat moss), and soaked them in a high concentration H2O2.
Here I disgussed with you guys about how to sanitize grow room properly: https://www.thcfarmer.com/threads/sanitizing-growing-media-with-bleach.162525
Then I rinsed the peat moss, and very carefully with attention on hygiene I planted my new seeds to easyplug which was placed in the peatmoss. Now after 2 weeks these seedlings looks the same like before! I freak out. I couldn't kill the virus properly, or this is not a virus, but if not then what? Never had this before. As I said I use peat moss, Advanced Hydroponic nutes, with enzimes and root stimulator. Same as before many times. No nutes on the first week then I go with a small doze to make something like EC 1.0 and pH 6.3. I'm using LED lights, like 250W and they are 50-60 cm from the plants so the PAR meter says it's something like 400. I attached some photos of the plants. Thank you guys, I really need some good advice now.

howdy,
looks like you have algae growing on the medium and to me a lot of the leaves appear water logged.

Hi! Yes Algae is growing a bit, but that never did anything with my plants. I didn't overwater, if this is what you mean? I only watered when the pots was light. Actually I did everything in the same way like before every time...

I overwater all the time, especially when mixing my own substrates carelessly. Some drain quickly and some hold the water like crazy (could be the pot not draining too). I'm just stating some quick observations and from my experience those leaves look very water logged. I recently overwatered my 100gal and was seeing the same leaf expression and purpling of stems. when you overwater for long amounts of time you'll start to see weird deficiencies/anomalies arise. Not saying this is your problem, but algae is telling me those have been quite wet for some amount of time.

also, some varieties deal with flood/drought better than others, my haze seedlings were very unhappy with the over watering, while my clone mothers didn't seem to care at all.

waaaay too wet,..

 

[GNick55]

got gnats??

 

[kumar]

waaaay too wet,..

the pots are light. Watered like 3 days ago. What can I do differently? Thank you.

 

[kumar]

got gnats??

No. And forgot to mention, the roots looks super healthy, thick and bright white.

honestly start over,.
and were those topped?

 

[GNick55]

what’s the temp and humidity?
i’ve never had algae growing so it doesn’t happen because it’s dry and has airflow

 

[Putthataway]

That’s a lot of algae on your soil.

about 28 degrees celsius, humidity is 60%. I had some fan running in the room too

i didn't top them. (if I understand your question correctly)

Rookie here! Algae does seem weird, I vote for a transplant and keep them going. maybe you get a cool mutation or something. in the name of science!

1. Straight peat moss has no drainage, like perlite, you are creating anaerobic root zone. (over watering) Seedling soil should have more perlite than normal soil.
2. PAR for plants that size should be 200 at the most. 400PAR is cooking them.
3. Too soon for nutrients, a little worm castings in the soil would be enough.

You should also have high humidity until they develop healthy root system.

"Over watering" can happen when you have no drainage inputs in the soil, like perlite. They need to dry out pretty fast to keep oxygen in play. So watering just once can be too much. This explains the algae.

 

[Sloppygls]

Over water to much you want them to suffer and then give them water to fix some might die the green stuff on the dirt not supposed to be there but should go away if you fix on time

Thank you everyone for the answers!
