This is Moonrocks ^ 3 weeks ago. No trouble at all, and also no nutrition either. The issues started cropping up as peak K demand started coming in.
Same with CBD Lemon Auto here:
Now, as far as what I know of cocopeat, unwashed / unbuffered coco will have an excess of K and Sodium. But it...
Symptoms have definitely progressed since then. A week ago, there were no real symptoms on the big boys GG#4 and Bruce Banner.
There are now. GG#4 more pronouncedly, and Banner minor.

In terms of nutrients? I haven’t used any. Just a couple of top dressings over the so far 12 weeks - earthworm castings, sprouted millet flour.
In terms of watered-in nutrition, as i mentioned - seaweed extract, potassium sulphate (only very recently), epsom salts in low doses probably twice...
So I don’t have an EC measure directly, but TDS in my water supply is about 120-150, so pretty low. Most waterings have been just water + aloe. Sometimes I add in some seaweed extract which would raise the TDS slightly. And then recently I added in the Potassium Sulphate at 1g/litre, which again...
Hey thanks for that Ninjadogma, appreciate the constructive feedback.
I had a feeling it could have been the lights. The biggest plants are at about 600-750 ppfd, smaller ones are closer to 500-650. I had lowered the lights about a week or so ago to bring it to these figures, and yes, that...
You’re right, it isn’t the same. And this is an issue ive run into before using coco + compost + aeration + amendments. Despite this, I have managed good yields and quality in the past. With unbuffered coco, i would have all kinds of issues - especially mg. With buffered, it generally seems...
Also to give you a better picture, it’s basically coots soil mix, but I substituted cocopeat (mg and ca buffered) for the peat moss portion. I also added some charged biochar (charged with homemade compost and some vermi).
I water using a 4 litre watering can. Add in about 10 ml fresh aloe vera...
Hey there,
So I haven’t been watering daily. Till recently, waterings tended to be approximately 3-4 days apart. I experimented, trying to observe the plants, even started weighing the pots at one point. Even now, I water only GG and Banner once every 36 hours or so. I started weighing them...
Hey Jez,
Nute lockout in a decently aged coots living soil? I thought the idea of such soils was to buffer against nutrient spikes via the symbiosis of plant roots and microbes.
I’ll check the runoff PH, but again, I was under the impression that a living soil like this should buffer against...
One more thing. It’s coots mix, but I used buffered cocopeat in place of peat moss (due to availability in my region). I bought low EC coco, washed it, and buffered it myself with calcium and magnesium.
Just in case that could be a potential contributor to the issues im seeing.
Hey Jez, PH is about 6.2-6.5. I use 20 litre bottled water cans, because our ground/tap water here is ridiculously alkaline (8-9).
The bottled water is filtered of particulates, contaminants etc, and sterilized. I believe they also add back some calcium and magnesium post filtration - as per...
Btw CBD and Moonrocks may look slightly wet in parts because I had foliar sprayed very low dose Potassium Sulphate. The foliar seems to have helped somewhat, that is new sugar leaves look fine, but the older leaves are still progressing in their crisping.
Hi guys,
First time posting here, so hello!
Ive got a decent number of grows under my belt, both indoor and outdoor.
My current setup is a multistrain (all from seed) - Bruce banner, Blackberry Moonrocks, GG#4, and CBD Lemon Auto.
All plants are in a 4x4 tent, with 550w full spec LEDs...
