  • There’s a University text book you can get really cheap second hand called “Plant Propagation and Practices.” If you read through the sections on the structure of flowering plants, herbaceous plants and olericulture, You will know more about cannabis cultivation than any youtuber, influencer, or cannabis themed company around. The internet is not a good resource, because most of the information is put out by seed companies, nutrient companies and purveyors of cheap grow lights. It’s not all awful, but the fact is they don’t exist to ensure that your plants are great and you produce lots of cannabis with very little effort. They exist to sell you their below commercial quality equipment, at an insane markup, when you can get identical, or better equipment from Alibaba. Advanced Nutrients has made an absolute killing splitting up N-P-K over and over again and selling it back to you at 300% mark up. The mermaid with the big tits on the bottle, isn’t for the plant, it’s for you!


  • Simplicity is everything. Light is a different school of thought. For indoor growing if you’re not adding Co2 a PAR of around 800 is sufficient, if you’re using a PAR meter. You can get away with a Lux meter (30 euro about) with a reading of about 70,000 if you’re using white LED’s, so, full spectrum grow lights. For the blue-purple LEDs you have to use a PAR meter. Which is substantially more expensive than a lux meter, but you can get a cheap one for a couple hundred euros. If you’re not at the stage where you want to buy a meter to measure the light. Just keep it at a distance so the plant doesn’t bleach. That’s the breakdown of chlorophyll which is the green pigment responsible for photosynthesis. If it’s natural light, just leave it be.



  • No worries buddy, I usually just lurk but I saw someone suggesting AI and I went ‘nope’. Correct, it all comes down to roots. You have 3 types of meristemic tissue, which are you bread and butter for growth. if you like. It’s where undefined cells are sent to gather and form new structures/tissues. The ground mersitem at the roots, the apical meristem at the nodes and the Procambium which is what creates your phloem and xylem, your transport tissue. Undefined cells are produced at the root meristem and then sent to areas of the plant for growth by chemical messengers called auxins. So, if your pH is out, the plant can’t bind essential nutrients and it looks deficient. If you’re oversaturated with salts/fertiliser it damages the root and diminishes the capacity to produce new undefined cells to send to these areas and again, it looks like it’s deficient. It also changes the priority of where they’re distributed, because now they’re also trying to limit damage that’s occurring at the root bed. You’ll notice that it’s the tips that get consumed first, that’s because leaves are energy stores. So, because it isn’t getting the nutrition from the transport tissue, because of root issues, it depletes those stored in the leaves to try and make up for it. That reduces the ability of the plant to photosynthesise, reduces the binding of carbon from Co2 using RuBisCo, which lowers the rate of cellular respiration, damages the ability of the plant to utilise nutrients from the feed and further slows growth. So, it’s like a knock-on effect.


  • Not True, that was the case with light water reactors, which were initially, only ever conceived for nuclear submarines. They were never meant to be scaled up. But, the US government canned research into Thorium and Natrium Nuclear reactors. Which can produce 1/1000 the amount of nuclear waste and can be fueled using spent nuclear rods from lightwater reactors. They create longer, more complete and sustained fission and we have had these designs since the 60’s. But the fossil fuel industry spent billions trying to demonise and delegitimise nuclear power because that would be the end of for-profit energy production. Now private companies like Copenhagen Atomics and Bill Gates’s Natrium are producing vastly more efficient and in the Case of CA, modular nuclear reactors. Like, the size of a 40 ft shipping container modular. It is super exciting stuff.




  • It’s root burn, or malabsorption. In short, you’re overfeeding. Ignore these deficiency charts, they only really apply if you’re growing in hydro with de-ionised water as your base for your nutrient solution. Tap water + soil means you have an abundance of all of your micronutrients already. If you’re in a physical media and/or using wholly organic nutrients, you don’t have a deficiency. Nutrient companies release these charts and try to convince you you need to buy a manganese supplement, or a zinc supplement. It’s just nonsense meant to prey on people that don’t have an education in horticulture and it will only make your situation worse. I can tell by looking at the leaf in the back (see the way the colour kinda fades across it?) that it’s not binding nitrogen correctly. The pale colour shift is classic. What I would do, personally, is flush the medium (I’m assuming soil?) with plain water, use approximately 3 times the water in litres as exists in the pot. So, if you’ve got 10 litres of soil in there, pass 30L of water through it. After that, leave it for 2 days to dry out and then add feed again at 1/2 the ratio you’re using. You’re already in flower, so you need to sort out these root problems today, because the root won’t recover the stuff you burn away.

    It’s a trap everyone falls into, the plant consumes more in flower so people up their feed. They consume more, but they don’t consume everything that you put in the medium. If you’ve already got a high-level nutrient solution in the soil and you add to it what happens is reverse osmosis, so the water is ripped from the root to equalise the osmotic pressure between nutrient saturated medium and the rootbed, because water moves from an area of high concentration to low concentration across a semi-permeable membrane. Flush it, give it two days, reintroduce nutrients at half the strength. I don’t know how you’re measuring the feed, but general rule is less is more. It’s been ages since I’ve done wholly organic growing, now I use salt solution nutrients in de-ionised water at 20-10-20 N-P-K, starting 550 mols/cm3 and moving to 800 mols/cm3 as you progress from veg into flowering. That is it, that is all the plant needs. If you are using organics, you need to keep your concentrations measured as well. It’s like jam, or salt preservatives you’ll overwhelm the bacteria present at the root base, so they won’t be able to break it down. That will further fuck with your pH and lead to more root damage.

    Edit: Just to add, the reason this “looks like deficiencies” is because when you saturate a plant’s root base to the point it causes burn, or malabsorbtion (see “lockout”) it can’t bind any of the essential micronutrients. Rule of thumb, if you’re in soil, not deionising your water. Every “deficiency” is caused by root problems and this is why you need plant scientists and not people who trust what AI tells them about plants.










  • It’s not NIMBY’s it’s oil. Look at The Simpsons, who’s the evil billionaire polluting the planet? Mr. Burns. The Simpsons airs on FOX, once you see it, you can’t unsee it. Even though nuclear power has killed less people than every other form of energy production. They’ve been trying to repressing and demonising this technology for the last 70 years. Coal Fire power plants release more radiation into the atmosphere in a single Day then a nuclear reactor will in its entire existence. Coal Fire power plants kill 1,000,000 people a year. We’ve had this technology for 70 years that’s 70 million people that’s more people than dies in World War II and we’re not allowed to even talk about it. Traditional lightwater reactors where enriched uranium rods are water cooled were designed for nuclear submarines. They were never supposed to upscaled to this degree. But the US cut funding to the Oakridge nuclear project because of pressure from the fossil fuel industry. This subliminal messaging, showing nuclear waste as glowing green goo is in everything. Video games, comic books, movies, it’s everywhere. They don’t want the public to be aware of the safety and energy benefits. These new Thorium salt reactors produce less than 1/1000 the waste of lightwater reactors and they can even burn waste rods from traditional lightwater reactors. That’s what the far-right is for to suppress the green revolution because that would mean the end of fossil fuels grip over the destiny of our planet. These people know global warming is real, fuck, trump just built seawalls around his golf course. This is why he’s threatening Greenland because war would mobilise NATO troops, removing support from Ukraine and give them an excuse to bomb the fuck out of Copenhagen to ensure the company working to produce finish their first prototype reactor would disappear. This is why Rogan and Jordan Peterson and all those dickheads support war and push climate denial.
