Anyone willing to take a look at these? Cannot Determine Cause / Nutrient Imbalances

I think you got some solid advice from these guys already, but maybe look into a surfactant to try to help get your pots back to the proper saturation levels. I have a bottle of yucca extract that I like to use from time to time. It helps make water "wetter" and rehydrate things a little more evenly from what I understand. I'm pretty sure people use soap, not up to date on brands or available products as I have plenty of yucca on hand for my needs, but you could look into Dr Bronners or just surfactants in general if interested.....

Appreciate that input, I was using Bronners as a suffacant this year in conjunction with neem... I am not longer feeding neem/bronners, but the problem started before. You're not the first to bring up yucca, and I think that will be my go to next year.

I was trying to do a living mulch this year, but everything got choked out by the shad of the plant. I like the idea of adding silica through rice hulls, thanks a bunch!!

"Super" soil should have what your plants need. So if your feeding habitually somethings bound to be off.

I run a gallon of water though 7gal fabric pots and my soil is >50% perlite.

2 plants of the same strain don't like the regime that works for your others and has for previous grows. Sounds like that strain dose not like the climate for one reason or another or has a specific intolerance/demand. What strain is it? What are the others?

Thanks for this input, it was one of the concepts on my mind. The buds seem to be doing pretty well at this point, and the other plant I have of the same strain isn't having the same issues. I think it might be a few things at play, water being a big one of them. I top dressed some amendments with the goal of increasing calcium and magnesium, and it seemed to help with the smaller of the two plants, but not as big of an impact on the larger.

It's my 3rd outdoor season, and I think next year, I will stick with the strains that have done best so far instead of testing new ones.

It looks like it is feeding off itself to me.
I don’t think it’s a deficiency. Maybe nitrogen because it goes dry??
Like ProPhet said it’s a big plant and it’s more likely a water issue.
Sounds like you go crazy with the food if already in supersoil? But I guess whatever works for you..
It looks like it’s had a shock and is scavenging from the old leaves.
maybe you could try sitting the grow bag in a tray and giving it wet feet if it’s a drinker?
See what response it has to that?

My main goal in feeding the ACT is to help the microbial life of the soil, not direct feeding of the plant. I do think my super soil mix will need more calcium and magnesium next year from some of the adjustments I made this year... But I think that water is the biggest issue here. I have increased the amount of water it is receiving and it seems to have slowed the issue down.

Your plants just completed the preflower stretch. They use a lot of n during this stage. Your plant is using the nutrients stored in the lower leaves to support the top development. Giving it more nitrogen now will slow the yellowing some, just don't over do it or Your buds will come out whispy and fluffy.
Next season, top dress heavy with a good 4-4-4 in mid to late July so the amendments have time to break down before the stretch.

Love this input, and I think you're right. I actually upped the amount of nitrogen rich amendments in my super soil mix this year, but it seems like it still might have been a little low.

Either way, The problem started just before the stretch and then got noticeably worse once it kicked into high gear. I am going to plan to top dress something to help supplement my bigger outdoor plants next year, and adjust the soil mix as well.

Thanks for the input regarding too much N during the stretch and whispy buds... I didn't go that route this time, and surely would have been let down to see that end result.

A shot of Neptune's Harvest fish and Kelp would've helped.

I was giving other sources of nitrogen into flower... The problem started and was progressing while I was supplementing ample nitrogen.

At this point, it looks like water was a big factor.

I am still thinking calcium and magnesium were at play too, and plan on amending the soil heavier with slow releasing organic sources next season.

Appreciate the input!

Pics of newest growth on the plants?
More info on what exactly is in the soil mix? Having seen multiple "super soil" lab tests It's hard to believe calcium or magnesium are your issues.
Dr Bronner has always been rough on plants and especially in the root zone from my experience. How much / how were you using that?

I'm new to FAA. Was recently given a bottle of home made Fish Amino Acids. Neighbor is into this Korean Natural Farming thing, before that I have been using store bought fish emulsion for a few grows, the idea with the fish emulsion is that it carries more than just nitrogen. Calcium (from the bones of the fish) and some Phosphorus. During the stretch the plant uses a lot of the Phosphorus.

It's raining today, but the plant in question is looking good at the moment. I can upload shots of the colas when i get a shot to be outside, but the yellowing has slowed.

I do believe water was a large part of the equation.

Super Soil Includes:
Base soil of FFOF/FFHF at a 3:2 ratio @6 Cubic Feet

EWC (20 Lbs)

Equal Parts:
Fish Bone Meal
Bat Guano
Seabird Guano
Blood Meal


Epsom Salt
Dolamite Lime
Azomite
Humic Acid

Rain water won't wash that out? Seems like it could flush that out of the soil.

While this does make logical sense (nutrients can be mobile or immobile in soil just like they can be mobile or immobile in the plant, and if they're mobile in soil, they can theoretically be flushed out), I haven't seen any evidence that it actually happens like that with organic amendments, even in pots.

Maybe it's because most of the nutrients are locked up in the actual amendment structures like bits of bone and poo and dead bacteria, rather than in pure ionic form, in which case those bits would have to be physically washed out of the pot...? I dunno for sure, but if it were the case that they could be flushed out, wouldn't forests and other natural ecosystems lose all their fertility pretty quickly after a few big storms?

exactly, and also part of why we allow the soil to "cook" prior to planting... It will help those amendments break down and become mobile for the plant and bacteria to absorb.

But he's in pots, not in the ground and flushing organic pots is considered a big no no .. so how do we cope with that when it's raining?

So it's ok outdoors to flush but not indoors... seems like an odd rule. I've seen popular growers do it like Soma with his rooftop grows. Just confused by the idea of it. Don't flush your soil...but hey, there's rain outside..with no worries about it .

Like I said, it does make logical sense, I just think the detrimental effects (if any) are way over-exaggerated, probably by indoor growers who have no experience growing outside.

There's about a gazillion people growing weed, tomatoes, and other annuals in pots on their deck/patio, who don't sweat it when it rains. That's not scientific proof but I do feel like it says a lot...

Good point, just mind twisted right now by it all. I could make a point for and against anything but this one has me on the fence right now. I'll have to take this to discussion to an outdoor thread. Because I'm all jacked up right now. I know a grower who would bring all his pots inside whenever it rained. So yeah, whatever works for the guy doing it.
