Well I knew I was coming to the right place for help but sure wasn’t expecting it at this level! Thanks for the thorough analysis. It does seem to have stalled a bit in growth compared to other plants - I suppose that is a symptom of malabsorption too?
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.
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!
You know I just might order that. I’m so tired of the pitch and all the SEO garbage and that’s before the AI slop started to take over. Makes learning about something such a hassle.
Probably close enough. This is the guy I used in college though. Anything from 5th edition up and you should be golden. Biology doesn’t really change that much, Universities just like to recharge you for the same information. I completely agree with you on the AI slop. I use a flip phone and a library card. Any dumb-dumb can get ChatGPT to create an article online to sell you something. University text books are dense and boring and the only place I would look if I wanted to learn a completely new skill. Good luck with the babies bro!
Also, sorry, just to add. Over-watering, having the medium wet all the time. Will massively reduce growth. You want Co2 at the leaves and oxygen at the roots. If it’s wet all the time it just won’t grow, you gotta let them dry out between fertigating. Pick up the pot, if it feels light, water it.
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.

Ah that makes sense! It’s really cool to understand the underlying mechanics.

Is this the one?

No apologies at all, I appreciate all the help. So lots of light and a bit of dry time between waterings is best, right?
