Gonn give 1g to purple and 1.5 to sour okie
Hoping to get 4 tops from the purple and then we will try to flower them.
Still didnt find out how much they eat its probably a lot more than now but i dont want to risk it soo slow and steady.sour is liking what he has now.and purple is trowing yellow bottom leafs soo i think she could take a lot more isnt growing much soo i dont know whats her deal...

What i noticed with ro for now the ph is almost allways perfect from 5.8 to 6.1 even today i added just the powder with no water and it dropped from 6.5

I had some neem mixed from a year ago and that was all i had sprayed one time but all i see is poop from the insects havent found any but last time i found 4 on the whole plant

Added 2lro and 3g to sour in hope of getting the ph down.soo i dont have to use ph-
It feels like shes doing a cube a day now that food is stronger and purple is growing the sidenodes.
Did anybody grew this sour i should see how she stretched maybe i can veg a little longer soo purple takes some spaces as well.
Currently i love the simplicity of the scrog but i dont like how hard is to work on the back row.maybe i should cut a hole in the middle soo my hand can go...and maybe i put the net too low but its allsoo a pain in the ass to cut the small leafs in the middle.i still have the old damaged leafs and its going to be hard to get rid of them.

Instrument is not the best but it should work.
Soo far plants look healthy.purple is pale green but its growing
Added some bowls of water to get the humidity up and one of those little sonic humidifiers little shit turns off every 6hours.i think it has 50ml tank but you can run it for weeks until it runs out imagine how much it contributes haha

Started messing with the vents if i turn it off(speed 1) humidity spikes vpd gets from 1.8 to ...
Looking likes its going for the better added a candle maybe we can get some co2

Title: The Physiological and Biochemical Consequences of Magnesium Deficiency in Plants


Abstract
Magnesium (Mg²⁺) is an essential macronutrient for plant development, functioning as a central atom in chlorophyll and a crucial cofactor in enzymatic processes. This paper explores the progressive impact of magnesium deficiency, detailing how declining Mg²⁺ availability disrupts physiological functions and ultimately leads to plant death when levels reach zero. It examines visual symptoms, metabolic dysfunctions, and the broader implications on plant health and agricultural productivity.

---

1. Introduction


Magnesium is a mobile nutrient in plants, meaning it can be translocated from older tissues to younger, actively growing parts. Despite being required in relatively modest amounts compared to nitrogen or potassium, magnesium plays disproportionately large roles in plant biochemistry. Most notably, it is the central atom in the chlorophyll molecule, thus directly involved in photosynthesis. Additionally, magnesium serves as an enzyme activator and is involved in the stabilization of ribosomes and nucleic acids. A deficiency in this nutrient—especially as it progresses toward total depletion—has profound consequences on plant vitality and productivity.

---

2. Early Stages of Magnesium Deficiency


When magnesium levels begin to decline, plants initially show subtle physiological symptoms, often first visible in older leaves due to the nutrient’s mobility.


2.1 Visual Symptoms
One of the first noticeable effects is interveinal chlorosis—a yellowing of the leaf tissue between veins, while the veins remain green. This occurs because chlorophyll synthesis is hindered, but mobile magnesium is relocated to younger leaves, sparing them initially.


2.2 Biochemical Impact
With less magnesium available, there is a drop in chlorophyll production. Consequently, the plant's photosynthetic efficiency decreases. Because magnesium also stabilizes ATP and acts as a cofactor for many enzymes, its deficiency disrupts carbohydrate metabolism, protein synthesis, and overall energy transfer within cells.

---

3. Intermediate Stages: Progressive Physiological Decline


As magnesium levels continue to fall, the plant enters a more stressed state with widespread physiological effects:


3.1 Decline in Photosynthesis
The reduction in chlorophyll becomes more pronounced, leading to a significant decrease in the photosynthetic rate. Less glucose is produced, leading to energy deficits.


3.2 Disruption of Phloem Loading
Magnesium is essential for phloem loading of carbohydrates. When Mg²⁺ is insufficient, sugars accumulate in leaves rather than being transported to growing tissues or roots. This imbalance can cause starch accumulation, leading to leaf necrosis and cell damage.


3.3 Oxidative Stress
Low magnesium levels impair the antioxidant defense system in plants. As a result, reactive oxygen species (ROS) accumulate, damaging cell membranes and proteins.

---

4. Complete Magnesium Deficiency (0 Mg)


When a plant has no access to magnesium, the outcome is severe and ultimately lethal.


4.1 Photosynthetic Collapse
With no magnesium to support chlorophyll production or maintain ATP stability, photosynthesis ceases almost entirely. The plant cannot produce sufficient energy to sustain cellular functions.


4.2 Growth Inhibition
New growth halts as magnesium can no longer be mobilized. The entire plant, including the apical meristems, shows chlorosis and necrosis. Root development is also compromised due to lack of energy and assimilates.


4.3 Systemic Failure and Death
Without magnesium, essential enzymes cannot function. Ribosome disassembly, DNA/RNA instability, and failure of metabolic cycles (e.g., Calvin cycle, glycolysis) lead to the complete breakdown of cellular integrity. This systemic failure ends in plant death.

---

5. Implications for Agriculture and Soil Management


Magnesium deficiency is often induced by imbalanced fertilization, acidic soils, or competition with other cations like potassium and calcium. Understanding the stages of deficiency can help farmers and horticulturalists detect and correct the issue early, preventing yield losses. Remedial measures include foliar magnesium sprays or soil amendments like dolomitic lime.

---

6. Conclusion


Magnesium plays a foundational role in plant physiology, particularly in photosynthesis and metabolic regulation. Its deficiency follows a predictable and devastating trajectory—from chlorosis to necrosis to plant death. Timely intervention is crucial in preventing irreversible damage, highlighting the importance of nutrient monitoring in sustainable plant management.

emptied a bag of peach lassi polen that i had in the fridge on them.i dont know if it was too soon? when is the right time to do it?

It's not about whether it's sooner or later, but about the speed from sowing to harvesting. Breeding is a long process, as fast as possible, everything is correct.This is when it comes to timeliness.

It helped a little but time to buy ph+ should have done it from day 1...

I noticed both plants have light burn maybe its because i fucked the magnesium but maybe last year i did daily uvc and plants where at 27cm now they are at 31...
Sour 879 5.78
Purple 547 5.8
Sour got a sip of 7g ph+ mixed in 300ml ro
Purple got 7ml
I guess i got that beautiful leaf i wished i would get from purple :)
For now i am noticing that diesel is growing buds one each branch like a z and purple is doing both sides each branch.and buds look bigger/longer hairs on purple.all and all love the look of purple

♡

Awesome read on the mag deficiency: ) thank you for posting!

Looking good in there. How are feeling about your pollination taking?

i put a lot of pollen inside the tent and the selfed plant did make seeds but i have no idea did it take or not this time... some hairs have browned but i don't really know what to look for.... even the last time i didn't realize i had buds full of seeds.

i am hoping it will work.

i am still not sure if this diesel is the perfect choice for breeding feels like its producing 50% since buds are growing in a zig zag but maybe it will prove me wrong as it all grows together.but compared to the purple its putting a lot more buds is it because plant is older and bigger and started flowering sooner still not sure

Cman started flowering haha.but i just killed it because one of the selfed seeds popped i planted it in its place.
I am honestly supprised i fought all the seeds where bad but i guess some managed to ripe :)
i wonder will it allso grow with 3 leafs as his momma

Yeaaa soo i think purple can eat a lot more than i have been giving it. I got soo used to the nice ec meter that showed any ec change now driving half blind feels strange.its gonna be a pain in the ass to figure out when i start overfeeding since half the plant is already burned from light and deficiencies

really happy with the canopy feels relatively even.only 1 branch on each side got a little taller than the rest.and the front is a little lower but still nice size buds. and sour looks like its gonna be fun to trim it :D
