Taco leaves & leaves lightening in super soil

[mortyb]

Hi,

I've been keeping this mother in veg for about 3 months now. She's in a 5-gallon fabric pot filled with 1/3 super soil (subcools recipe) & 2/3 FFOF + FFLW. She's been fairly healthy until 2 weeks ago where she started to show signs of a nitrogen deficiency (oldest leaves started to yellow). I figured she finished all the nutes in her super soil, so I top-dressed with a 1-inch layer of super soil & now it seems like she's worse.

I'm seeing even more yellowing now & her leaves are very skinny & tacoing heavy.

Now



1 week ago (before top dressing)



2 weeks ago (barely any yellowing)

Check ph of runoff on next watering. Something is off. The leaves on the left side of the now photo looks to be yellowing between the veins. Magnesium deficiency if I remember correctly, yellowing from bottom sure looks like low nitrogen. If your ph is out if whack it cant absorb anything. If you dont have a grow bible do a search on it. It helped me tremendously. I liked to killed 3 autos from nitrogen burn and if I didnt have the grow bible I would've lost all 3. ILGM has one and a plant care guide that's useful. Both can be downloaded, you'll get the pdfs in your email.

Are the roots supposed to find that top dressing? I don't get it. I would just start feeding them something.

To be honest, I'm real new especially to organic growing. I've been reading a lot of people top dress with super soil, so I figured I'd try it out. I mixed in the super soil into the first inch of soil & watered it in. Since the super soil contains lots of amendments & has already started to break some of these down, wouldn't this feed the roots & replenish the used up amendments in the soil?

Ah the plant to the left definitely has some PH issues. I'm not seeing any of those Issues on this plant though. I'll definitely check the runoff next time though.

The amendments in the soils can be used up in some cases fairly quickly, especially if it's a heavy grower. Adding an inch will replenish some, but gets spread thin throughout the media. If it doesnt begin to show good growth at the top of the plant in a few days I'd recommend feeding it something. I'm running a potting mix, and, if I dont add nutes to my water every other day, itll begin showing signs after a few days. Kudos for trying organic. I'd like to try that one day and see how it goes. But for now I'm rocking the potting mix and fox farms nutes. So far so good.
