I'm going to start playing with fertigation as a way to maximize the O² exchanges.

After 5 years of growing I’m still working on watering. Some will think that’s nuts but I think so many issues come back to watering for a lot of grows. People chase all sorts of things needlessly.
I grow in living soil with good nutrition, light, and environment so watering is really the other piece of the puzzle
Keep working on it

Thank you, everyone. It seems the issue is with my watering.

[Rootsruler]

You really want to wet ALL the media not just on top of the root ball.

When you water the entire media the media in the rhizosphere, the area adjacent to the roots, will dry first as that is the easiest for the roots to access. Once it gets dry the plant will signal the roots to go looking for more water. Having moist media beyond the root ball will get your roots to grow larger and longer.

I don't elevate my pots. I leave them in plastic bins and let the runoff resoak back into the cloth pots.

No rinoff in a soil grow without nutes. You wash out the goodies.

I don't know. I don't use fabric pots.

I’m not getting much runoff because my pots are on the floor. In the next few days, I’ll lift them and start watering to achieve about 10% runoff. Could the problem be that I’ve only been watering around the center near the seedling?

[Bluey]

Are you getting much run off? Try for almost zero run off.

I'd spread out the watering a bit and see if you can give it a bit more. I'm not actually sure what is causing the deficiency I doubt it's a lack of any calmag, I think the problem lies elsewhere. Lift the pots off the floor. Be conservative with light.

[Eclipce]

I’m growing in soil. I’ll keep an eye on the top leaves. If the situation doesn't improve, should I give сalmag?

[Bluey]

Are you growing in soil or a mix of coco?

Looks like the beginning of a calmag deficiency with the slight loss of pigment and rust spots beginning to appear. Often typical of a coco grow.

If you just started nutes give it a bit to see if you get further changes. The damaged leaves won't fix even if you've fixed the problem. Watch the top leaves too.

Help! Leaves are getting spots.

Hi. spots appear on the leaves of 2 plants(Laughing Buddha and Сritical Kush) out of 5. I noticed 5 days ago. The plants are 20 days old after planting in the soil. The spots appeared before I started giving them nuts (I use advanced nutrients pH Perfect® Grow, Micro, Bloom). I water about every 2 days with 500 ml of tap water. The Mars Hydro FC 4800-EVO LED lamp is 45 cm above the plant and works at 65%. I think it's a potassium deficiency.
What do you think it could be?

I'd reduce EC, especially nitrates.

New growth should be light green not dark green indicates a bit too much N to me.

Nute burn on leaf tips also

Overall though looking pretty good.
