I've been researching on many different sites but can't figure this out. I'm growing a blue dream and northern light autoflowers. I'm getting yellowing on both plants that are in 5 gallon fabric pots. It's a super soil setup using nature's living soil and basic spring water. So why so much yellowing or is this amount normal? I believe I'm in mid flowering.
Why are my plant's leaves yellowing?

If you are feeding properly, you may have a lock out. Yellowing from the bottom up usually points to N deficiency. By the color of the other leaves.. they are hardly lacking N.

Check those buds for bud rot. The dying leafs like that can be a sign that the buds may have some rot since the plants don’t look hungry really so that’s where I would start

Good point.
I checked really well for bud rot but don't see any of the obvious signs. No mushy stems, no mold, no discoloration, etc. Other than the yellowing they seem healthy.
I just wanna make sure. I'm running super soil with an organic soil as top 2/3 of pot. I thought the plant will feed from the bottom portion as it needs it. This should result in no nutrient deficiencies unless of course I water to much and wash those nutrients away. I personally don't think I'm over watering though.

Are my thoughts as stated. A pre made soil on a commercial scale? Spring water?
I offered. Best wishes in sincerity. Stay organic. TY.

It's far too early for bud rot, you have a ways to go yet. Try watering from the bottom and let the plants drink it up from the planter tray.

these "different layers of soil" in one pot are creating too much problems and may be the reason for this mismatch of defs & tips yellow.

Try tap water at 6.6 to 7.0. It will reduce the available N and give a bit of mag. A true living soil needs no proper PH so to speak. These fake soils that are crazy hot do. Or they burn or starve your plants. Build your own dirt in time. You will see things as you grow. LOL.
It's a super soil setup. The bottom 1/3 is fox farms soil mixed with nature living soil.. The top 2/3 is just fox farms.

Sounds like the soil mix is over thought and underconsidered.
Good luck

Any leaves that are exhibiting chlorosis (yellowing) will recover, necrotic lesions (dead blotches) will not. If a leaf has an issue like yours that developed necrotic lesions, the plant will sacrifice it. It will exhaust it of any and all stored nutrients.
Your not N deficient, your P uptake is struggling. Rethink your watering regime and allow the soil to dry out some. P is inhibited from being taken up when the substrate is too wet for too long and/or too cold.
If you see no improvement then your deficient in P, or its your pH(KCI) despite your pH(h20) being in range.

I am running LED's and my temperature is at 72o.
Why would I see improvement if I let the soil dry out or was that a typo?

Can you get it hotter?
