Please Help Diagnose Sick Plant in Bud Cycle

[DMTspice]

Hi everyone. I have a thread similar to this active in cannabis infirmary. My grow is organic and someone recommended I post it here.

For reference purposes, this is a link to that thread:
https://www.icmag.com/ic/showthread.php?t=223086

I've already received awesome feedback from the guys over there and they gave me a few ideas to go on.

***SOIL COMPOSITION***
6 parts compost
2 parts EWC
2 tbs gypsum
2 tbs kelp meal
2 tbs bone meal.
Feeding Blackstrap Molasses and Alaska Bloom Fish Fertilizer (since I started having problems, I've stopped feeding. Flushed it twice with tap water)

Ph runoff is a little low, around 5.8. I've been trying to remedy that by adding a baking soda to my water before feeding.

Temps range from 72-79

I'm 26 days into the bud cycle. Symptoms are pretty much what you see in the pictures. Fan leaves start to yellow with those rusty spots along the veins and they eventually curl up to a crispy brown. Whether this is a deficiency, ph lockout or toxicity, it's now reaching the bud sites.

I have a few things on my agenda to remedy this problem:

1. pick up some crushed oyster shells and epsom salts (my dolomite substiute).

2. Mix up some fresh soil and transplant into a bigger pot.

Looking for additional feedback, suggestions, comments, opinions...

Thanks in advance!

Alaska bloom fish fertilizer is not organic. I'd go for a fish hydrolysate product like Neptune's Harvest or something of that nature.

I'm trying to keep it as organic as possible. N, P & K aren't carbon based so they're not organic anyway, right?

i think I saw Neptune for sale at the place I got Alaska Fish Fertz from. Thanks for the tip.

Just out of curiosity, do you know why Alaska makes their veg organic but not their bloom? The veg says organic right on the bottle- whether or not that's a true statement I don't know.

heat stress

 

[DMTspice]

Heat stress, really? That's one I haven't heard yet. What makes you say it's heat stress?

I would love for it too be heat stress. It would make my life a lot easier. All I'd have to do is move my lights a few inches back.

the chemistry term "organic" does not mean it is carbon based. I'm not sure why people keep spreading that definition.

"organic" is a a somewhat arbitrary term in chemistry denoting a collection of compounds associated with life processes.

CO2, on of the more common sources of carbon, is inorganic.

Thanks for the correction man. Here are some pics from today. shits getting crazy. I've been pulling out all the affected leaves so once all those are gone it's going to start attacking the buds. What do you think guys, should I go ahead and transplant?

At the earlier stages I would say mg def.... but at this current stage I can't really tell cause if it is Mg def, then it went too far. At such a stage I have not yet been.

imo theres your problem.

im going to go with some sort of lockout.

EWC slurry to the rescue.

 

[guest2012y]

What was the reason you added gypsum?..where are your drainage/aeration amendments?

I've grown plants in straight EWC and compost alone...but this is not an ideal medium for indoor potted plants...you need drainage and aeration indoors.
Alaskan fish is an Emulsion...it is made using heat,which concentrates the heavy metals from years of industrial pollution accumulated in the fish.

Fish hydrolysates are made using enzymes to break down the fish.

 

[DMTspice]

Capt.Cheeze1- I'm not sure why the gypsum is in there. I copied a recipe that and gypsum must have been one of the ingredients. To be honest, I'm just starting out in organic soil and this is obviously not the perfect mix.

As far as drainage and aeration, I have 2 parts perlite to 6 parts compost. I just want to transplant the damn thing I think that's the only thing that's going to save it.

I don't think foliar feeding with epsom salts is doing a damn thing at this point. I feel like I need to take immediate action.

So this is what I'm thinking:

Mix equal parts compost/EWC/perlite. And put her into a bigger pot. Then continue feeding with equal parts Alaska veg and bloom?

 

[guest2012y]

Compost and EWC alone have enough nutrients to grow the plant through a cycle alone at that rate.
I'd increase the diversity of the medium by adding peat or/and coco. If you add peat..add dolomite,oyster shell and/or agricultural gypsum at the recommended amounts. I'd ditch the Alaskan and go for something better.
There's kelp meal in the mix..so why spray the plant with epsom salt to try to fix the lockout? The problem is in the soil..it's not a complete and balanced mix. You shouldn't have to be feeding anything if you've built a complete soil....continuing to add the Alaskan products can't be a good thing.

Build a better soil and start over..many fine threads here with great soil mixes...why there's one in my sig..

 

[DMTspice]

Problem is that I was rushing to get into organics and I stocked my shelf with whatever products I could find locally. I mixed my soil which was incomplete. Later I picked up the Alaska fertz to make up for what was missing in the soil. Obviously the whole thing was poorly planned.

hmm this is weird...in the earlier pictures I was going to say it was just that the strain tends to yellow when flowering...but it's nowhere near time for that to happen. Yeah man something weird with nutes... I've never seen leaves actually go brown like that. Someone will know.

 

[DMTspice]

It's just fucked up man. It's my only plant right now that's why I'm trying to do everything I can to save it. If I had other ones I probably would have given up a long time ago.

I'm just going to through the whole thing into a new soil mix and if that doesn't help fuck it.

 

[DMTspice]

There's tiny white bugs crawling all over the root system!!!!!!!!!

I got a a super macro shot. This is not actual size, you can barely seem them with the naked eye. Anybody know what these critters are?

 

[bobman]

oh boy what else can go wrong. those could just be springtails. do they hope like a flea when you scare them? if you are going to mix a new batch of soil you may want to investigate lime pellets. they should be at most hardware stores. search lime at homedepot.com there are a couple of different products.

 

[bobman]

your roots look nice and white that is a good sign

 

[jaykush]

springtails they are, no worries.

 

[guest2012y]

Blind springtails...beneficial organic matter decomposer..harmless and a great indicator species.
