What could mean this yellowing?

Hello!

Hope everyone had a happy new year!

I have 2 autos and 2 photos (photos in small coconut pots, autos in big ones), they have some kind of yellowing (it’s showing more irl than on the photos).

What could it be?

Cheers!

What kind of lighting are you using?
Soil looks way too wet for the size of plant. And though node spacing looks good it may be missing some important parts of the spectrum. My be able to lower the lights or turn them up if adjustable.

Hey!

Light is a hlg 350 diablo.

I ve just watered them at the moment of the pic.

Would you lower the light intensity or up it then?

I mean, except for the leaves being lighter green they seem healthy. My guess would have been light spectrum but those are good lights! Could lower it but node spacing is good. What medium are they growing in? And are you adding anything to the water?

Hey!

Growing in soil, using terra aquatica tri part. I did not give fert for 2 weeks~ cuz the soil has some already, could be the reason?

Would you lower the lights or up the intensity? Rn i m at 141w, next on step on the manual dimmer is 215w.

I’m not able to view the photo. Is it overall or at the center of the new growth?

You could probably bump the intensity to 215 for a little while. Then up again. Haven’t personally used hlg but they are highly thought of. But I’d think you need at least 400watts by last weeks of veg, early flower. Others likely will have better info on this as I’ve only ever grown one at a time.
What type of soil are you using? Most soils seem to be preloaded and i see no ill effects from waiting a month to start fertilizers. But type of soil does make a difference!
You got good light so you likely have good soil and already know this lol!
Old guys tend to ramble…

Hey @Shroom , is it possible for you to upload the pics here instead of the link? Might be easier for others to chime in

Hey, here are the pics :slight_smile:

Yellowing is a little worse irl. The small auto almost stopped growing (like it’s barely growing at all).

Cheers

If those were mine I wouldn’t be worried about them. Even the small one looks good. I always have one that lags behind but somehow catches up after I flip them.

Agree with @GoneFission . Look okay.

@GoneFission what they said.

Autos are just lil fussy drama queens sometime. Have had some grow like they were shot out of a canon. Others germinate, wait 2 weeks, then decide to grow.

Looking good, no worry if they where in my tents.

Cheers folks :slight_smile:

After upping the watts / giving a lit more nuts (thought the ones in the soil would be enough, seems not) / switching light from day to night (heat), they are gaining back some nice green!

And yea, fml autos. 2nd time trying, 2nd time it will be meh I guess. Back to photos, the experience was fun, but they are way too stressful for me with their auto switch to flower.

Also rip, skunk purple not growing at all I guess it’s stunted.

Cheers!
