Soil grow, flowering stage, which nutrient(s) would help?

[MrPNW]

Being my first grow I didn’t fully understand the nutrient needs when I started 01 October.

I planted in 3 gallons of plain organic soil, some weeks later I found out about Nature’s Living Soil and moved the content to 7 gallon pots surrounded by NLS mix (hindsight: I should have done their super soil mix).

They’ve looked pretty good after dialing in the environment and using compost tea every couple weeks.
I switched to 12/12 on 01 December and in the past few days noticed some yellowing. I added some NLS into the first couple inches per their top dressing directions and covered that with a new layer (1-2”) of some living soil mix I had leftover from the transplant. The soil had settled providing this room.

I’m not sure if this will be enough nutrients to take me to the flower 60-67 day mark.

At flowering time I did the following;
Moved the light dimmer up from 80% to 100% (per SF’s new chart)
Lowered the light from 30” to about 18-20” (per SF’s new chart)
Lowered the temp range per GWE’s chart
Lowered the temp range per GWE’s chart

This was Sunday. It’s easier to see the change in real life. The yellowing is mostly up high, but oddly on the rear left plant, half of it remains darker green (the half to the right). The smallest of the 3 plants is at rear right and has the most yellowing. It seems I have 2 phenos and that yellower one is twin to the one I moved indoors to be a mother and that one has never changed in color (beautiful dark green) with all 4 getting the same soil treatment.

So is it all the environment changes listed above (stressing the plants) or is the plants eating up all my supplemental nutrients due to flowering?
If I need more powerful nutrients what would you recommend for soil?

MrPNW hi again, I'm not seeing the yellowing you are talking about but normally it is magnesium and a tbs of epsom salt/gallon of water should help with it and won't hurt if not. If you are wanting to stay all organic I read a good article about organic feeding https://homesteadandchill.com/how-to-feed-cannabis-organically/ I don't know what NLS is so no help there. I use a sf and during flower I keep mine at 15" 100% I'm having a little trouble now with some blue dream being sensitive to light so obviously there's never an exact setting

MrPNW Just read your bottom and duh NLS. I'm growing in living soil now and as long as you haven't killed the little critters in your soil you should be be ok to harvest with teas. Again check out the link above for some great ways of feeding. Plus a compost and or worm poop tea will revive your soil critters

This is the NSL recipes I’m following;

Top Feeding
Put a very thin layer of Nature's Living Soil on top of soil and water for a boost in nutrients and microorganisms. Apply the diameter of the widest branch or all the way to the container wall.

Compost Tea:
Add 2-3 heaping tablespoons of concentrate and one tablespoon of un-sulfured black-strap molasses per gallon of water and let stand for 24 hours.
[I also added some Plantonix seaweed extract to the mix]

Living Soil:
1. Thoroughly mix 1 lb of Nature's Living Soil concentrate for every 5 gallons of organic potting soil to make a ready to use Living Soil
2. Make a small hole, about the size of a 16oz cup, and fill with organic potting soil.
3. Plant and water from seed to harvest
[This is the recipe I went with to surround the 3 gal original potting soil with in the larger 7 gal pots]

That is very similar to what I use. I use earth dust it's 2 bags of organic amendment one you mix in your soil making it a living soil I used my old happy frog and still using it. You mix the first in your soil and one week before flower you top dress em with the second mix and another top dress one month into flower. Throughout the grow you just water with filtered tap water no need for ph testing you just water. If you see any kind of deficiencies you can make a tea from bag 2. I just started flower on my second grow with this stuff and I'm not planning on changing products I'm happy with it

 

[MrPNW]

Now that I fully understand the Subcool Super Soil concept I’m going that route entirely on my next grow with the solo cup going straight into 7 gallons of it.

NSL site info
Super Soil Technique:
1. For containers 5 gallons or greater use 3.2 ounces of concentrate per gallon of container
2. Fill a container 1/3 full with the concentrate and potting soil and mix thoroughly.
3. Fill the remaining 2/3 of the container with base potting soil only
4. Plant and water from seed to harvest

I believe that you are making the right decision. I'm liking the organic living stuff and I have shared some of my last grow with friends n family and they said that it was definitely better tasting than other weed I've given them. Of course they're getting free weed so they're not gonna complain but I always ask em to be honest with me about my weed because I want to know obviously how I'm doing.
I really don't like having to transplant but I always start in cups because it never fails 1 or more of em will stretch or grow sideways and it's easier to fix when you transplant then if they're in their home pot from the beginning.
Good luck, we'll see you around I'm sure 👍

I’m actually thinking about doing an experiment combining their two techniques. Begin with a large Solo cup of plain organic soil for the clones/seedlings and transplant those into the 7 gallon pots with the first 1/3 super soil mix, then 2/3 with the living soil mix.
I’m hoping the large Solo will be enough buffer for the young plants before hitting the living soil and finally the super soil at the end.

My plants need watering about every 3 days. Since the one showed some yellowing I’ve been watering them with compost tea.

Day 1 - I fill my bucket with 3 gallons water. The “bubble” lid aerates it for 24 hrs to dissipate anything in this city water (which is nice water).
Day 2 - Add nature’s living soil, molasses and seaweed extract. Brew
Day 3 - Water the girls.

Day 26 in flowering.

I just ordered some of this today. I’ll be using this instead of NLS’s Original soil to make compost tea and top feeding.
