Leaves diagnosis

[GreenPeace22]

Short, brief and to the point, I'm looking for a diagnosis and a cure for this.
Thank you!

Probably overwatering. It's the most common mistake for novice growers.

Growing in Coco, watering once a day, at the exact same time every day...
Also, how does overwatering explains the yellowing?

Stress.

No shit...
I thought she was happy...

Overwater would be stunted growth and droopy as hell. I think you need to lower your ppm and raise your light and lower your temps

 

[iDab666]

And yellowing can be caused from over watering even though I don’t believe that’s the case here. You can cause a nutrient lockout by overwatering. How many ml’s are you feeding ?

 

[iDab666]

Your leaves are definitely showing signs of heat stress ( leaves cupping up) with minor yellowing. It will get worse if you leave Untreated.

Poor root development from low DO in the medium which lead to --> Nutrient lockout from overwatering.

Raise the lights. They need very little at that stage.

I'm watering with distilled water, 300 PPM, (nutes + cal/mag), pH 5.8
It ain't that much...

Then I’d start with the lights. Raise those up a bit and you should see the cupping ( what the outer tips of your leaves are doing ) start to flatten out. I’d consider some micronutrients for the yellowing. If the damaged leaves don’t bounce back as fast as you think they should don’t just cut them off. Pay attention to what and how your new growth is doing.

Roots look nice to me. Even the surface of the soil has white porous roots.
I'm confused...

the yellowing is more than likely cause from heat / light stress though. So I would definitely start there and if you see any more yellowing after you have raised the lights and it’s been at least 12 days then I’d consider looking for some micronutrients.

Right now she is under one 23 true watts (103 equivalent) CFL bulb, 6500 Kelvin, at 2 inches, maybe 3.
As far as I know CFL needs to be close to be efficient.
My main flowering light that I use is a HLG QB 135W Kit Rspec, should I use it instead of the CFL?

Don’t get your self all worked up. You’ll figure this all out it’s just a matter of trial and error.

Okay yea it’s 100% your lights being to close.

 

[iDab666]

I’d raise the lights to about 15” away from the top of the tallest plant

No just raise the cfl about 1 foot. Use the other one for flowering.
