Issues with autos

Hi all, currently noticing some drooping on my 23 day old cheese autos from fastbuds. There are on a 20/4cycle 60%rh temps 25.4°c. I'm very cautious with watering as on previous grows I have overwatered. They are in 12l pots with living soil. I can see some signs of high nitrogen levels and was hoping that during the stretch it would use up a fair bit. Any ideas what's causing this? I wait untill pot is light(not completely though as was advised not to let it dry completely using living soil)IMG_20231030_064424.jpgIMG_20231030_064424.jpgIMG_20231030_064424.jpg

They look pretty healthy. Wrinkly looking at some leaf ends suggests you may be overwatering, which would also cause them to droop. Let them dry between waterings. They may also be running out of room and look like they should ideally be up-potted. If roots don’t have enough room the grow can suffer too. Just some guesses. Others might have more insight.

Usually I run the 12l pots with autos and don't get a droop, maybe the fastbuds genetics need more root space. Don't really want to repot them at this stage and cause stress

How high would you recommend, I'm currently at 30" above canopy, 200w wall draw led

Do you have a dimmer on the led? They can only take so much light a day, so you generally don’t need to run the light at full blast when using 20 hour cycles. I never went above 75% or so on my last auto grow running the lights 24 hours (an experiment). I hang them around 24” from the canopy.

I've kept light at 30" and dimmed to 75%. Let's see if that helps

Not as bad as this, more since preflower

Ive had this before but with an older brand of soil.

Could try bumping the temps up to 27-28c, I’ve seen others plants respond well to that, especially using LED.

If the temp doesn’t resolve it’s a moisture/soil issue.

But your plants are a good size for 23 and are healthy so should do well. Usually the droopy ones get all perky come proper flowering.

Could also be rapid growth, they do droop then perk back up at various points.

Lots of things cause drooping but don’t worry unless the plants slow in growth!

Yeah they are growing fine, just strange as usually my plants are praying, I'll let pots dry fully before next watering

Different strains have different tolerances to soil moisture.

In my experience (unless they are completed soaked) is that letting them dry more doesn’t fix the droop. High salt content can make the plant droop too

Would I still get a salt build up when using organic dry amendments'

Could adding a cover crop at this stage help with soil microbials and help if over watered(I e the cover crop would draw any excess moisture from the soil?)
