Autos In cocoa

[AutoNM3]

As I wrote the solution now is to flush and start over with a liquid feeding schedule, even if it is not organic. Get the cheapest try pack from any brand and go ahead. The plant's are considered sick and this is the way to cure them at this stage. Also add an aspirin to each plant's water to help it recover.
If you have the Flora line OK use this after the flush in the suggested doses of all the range's products. Dolomite lime I never use because it messes up the ph and takes ages to release magnesium and calcium. If you use a liquid cal Mag there is no need for the Epsom salts. They are a good solution though. If you choose a ready liquid cal Mag prefer the GHE and avoid the AN product because it has an extra N 4, which is too much.
Unfortunately you entered in a vicious cycle of nutrient imbalance and autos are not easy to deal with such a stress.
Next time don't use the same amendments you started with this time . If you want to have a rich medium don't use these universal fertilisers with NPK 2-2-2 or 4-4-4. They are not good for cannabis, they are for the lawn in your garden. Roots organic is as I get it in that category. Get an organic slow release grain fertiliser for roses or strawberries that has NPK values that are around 7-6-12. And crushed seashell powder or granules for an organic source of cal mag. Add 2 table spoons before planting and every 20-30 days add 1 or 2 table spoons depending on the container size. Every 15 days add to your water a bio-activator with humic and fulvic acids and kelp extracts with aminoacids as a bloom booster.
Soil is more forgiving than coco. The best choice is to get a potting soil mix from a gardening store, usually their base is peat and they have extra perlite, coco and compost. You can get 40-80 liters at around 10 euro/dollars. If you can make your own mix then go ahead it is even better. I also don't buy the overrated soils of biobizz (they dominate the market here in Europe, as Fox Farm does in US) because of crap quality and high price. Coco you can reuse, the rest might need amendments. If you want to stick to solely coco it is fine but prefer liquid fertilisers because they act immediately and you can control easier. In such a case prefer either the Biobizz line or the GHE organic one and follow their schedules without deviation.

The pics above show classic russet mites problems. Textbook. I’ve racked my brain about nutrients over the past two or three weeks. It’s good to know that those weren’t even the problem. And I do think admitting amending with the 2-2-2 is great especially when the ingredients are exactly what you need for long time stability;kelp,alfalfa,etc. I really take to heart a lot of what you said. Mostly true.

I cannot tell if you have a pest problem from the pictures, you need physical proximity to verify. If you really have one and you did find pest signs after a careful inspection then things change totally. I hope you can solve it quickly and with no casualties. And sterilise everything before next grow, not only to get rid of the pest but also of the diseases, fungal and microbial that pests carry with them..
About the nutrients, it is my sincere advice that you must switch from the general purpose 2-2-2 fertiliser to a more bloom oriented ratio of NPK when growing autos or doing photos 12/12 from seed. General purpose fertilisers are an excellent choice if you grow photos and ideal to provide what the plant wants during vegging. But with small palnts that have an insignificant vegetation period, like autos, it is an option that both delays flowering because the ratio of nitrogen is high and also you need to provide a lot of quantity for the plant to uptake the potassium and phosphorous it needs.

It fascinates me to see others following my footsteps and have hardships as I did when I first started growing photos outdoors.
Experience now tells me to keep things as simple as possible. This way there is less to go wrong.
I've always grown in peat only. And with time you learn the quirks of peat. Now I'm into coco and it aint easier or perfect either.
Both require learning and adapting to growing in different mediums.
I use to use GH 3 bottle setup..now I only use a $10 bag of MegaCrop and a little recharhe. My grows have quadrupled in size and better than doubled in quality.
Why??...cause the plants dont have time to suffer. Recoup time is quick with less going wrong.
We tend to over complicate things.
I've noticed with time here on the site. The most impressive grows were the most simple ones.
Regularly.
Its hard to argue with success.

Very important to note that quantity is not the main aim but secondary to quality. Quality you can only have if the plant is happy. If the plant is happy then it will reward you with very potent weed.
By getting to know how to make the plants happy, not only you will have top quality but bigger quantity will be also be an outcome. By trial and error and keen observation you will learn what makes each strain happy. Not all strains respond well to LST for example, which means that you cannot aim to a high quantity from individual plants so you need to grow SOG and many plants. Or SOG is limiting a very bushy bad tall plant and SCROG might be the solution. But most of all you must give a plant the best possible conditions for its growth, in nutrients, water, climate and light.
Pests are in the game as well but a well fed, aerated, watered and illuminated plant can overcome most of them with no real effect on its yield.
Medium is not the factor that will determine success, but soil for example is more forgiving to mistakes. If you exploit the medium's advantages then you can overcome most issues. I have seen many organic grows in soil that dwarf most hydroponic grows in quantity and of course quality is beyond comparison. And that is with only water and organic nutrients.
The rule to follow is lots of light, lots of air, minimal water, minimal food, a steady tolerable temperature and progressively medium to low humidity. These are pretty basic steps that keeps things simple and productive.

Thanks a whole lot for those last two entries man. I learned a lot on that.
However, I’m sad to say I pretty much trashed the whole room. Pretty well disgusted I am ——here’s a picture of one of my leaves on the last plant I just destroyed.
The next two pictures, one is a picture of a root ball on an auto that I had set inside of a larger bucket after about 25 days because the roots were coming out of the bottom of the fabric pot. Look at all those routes before the russet mites got it!
And then the last picture is what they do to a fully flowered Chem OG plant. You see how they eat the truck comes from bottom to top. I salvage the top of that bud but that plant I lost about 5 ounces.
I’m literally more pissed than I think I have been since I started growing and I’ve had a good year and a half worth of learning. Damn those fucking things
