That’s the obvious difference. The standards for indoor growing have changed drastically. No one would harvest a dark green plant and show it off 20 years agor. Almost every indoor Led grow produces plants that turn ugly Blue with ugly red petioles and the aroma fades just as fast as the leaves turn Blue. Many indoor plants I observe go straight from yellow to blue, entirely skipping the natural green color range of healthy Cannabis.
I’ve always heard that Phosphorus deficiency causes plants to turn Blue,but I’m no expert. My indoor plants turn Blue when I run artifical lighting at full capacity, and I’m having no luck raising Phos and/or Potash after symptoms occur. Let’s see what the experts have to say about nutrient imbalances that cause plants to turn Blue.
This debacko guy says -Phos makes leaves fade to purple. Is that indoors or outdoors? Couldn’t tell you. But guessing from the fact I had suffering, Blue, necrotic indoor plants with zero purple, that immediately turned purple when placed outdoors, I’m guessing outdoor phosphorus deficiency and Led phosphorus deficiency produce different symptoms. Let’s find a new expert:
This scientific journal shows the following symptoms for -Phos. This is the type of suffering I see commonly, everywhere, indoors. (Which will turn purple only when set outdoors for 18 hours.)
This study was conducted under glass, (which alters light spectrum?)
Why do the experts provide conflicting information? Is the light spectrum actually changing the way deficiencies are expressed, or the way nutrients are metabolised?
There’s the trope about Cannabis users using too much phosphorus. Is anyone actually measuring the sap to conclude this, or are they measuring soil and leaf tissue, erroneously attributing availability to unavailable phosphorus that is bound up by other, excessive minerals?
Or is phosphorus deficiency not the cause of all the ugly blue indoor plants that drop their leaves weeks early?
I Google around for any mention of dark leaf deficiencies and find;
Phosphorus deficiency:Dark green coloration with tips of leaves dying.
Phosphorus deficiency: Older leaves turn a darker green followed by a purplish tint starting from the leaf margins.
Phosphorus deficiency: Leaves looks stunted and turn dark green or even a deep purple color (almost black for some plants). Leaf tips may look burnt.
Phosphorus deficiency: Sometimes the stems are not affected, but in some cases the only symptom of the deficiency is bright red stems. The leaves start to darken, turning a grayish, blue or dark green. Sometimes the leaves look shiny.
Phosphorus deficiency: When you notice a plant with purple leaves rather than the normal green color, it is most likely due to a phosphorus deficiency.
Phosphorus deficiency: Phosphorus deficient plants are often mistaken for unstressed but much younger plants. Under severe deficiency conditions there is also a tendency for leaves to develop a blue-gray luster.
Tldr:
Why are indoor grown blue plants with fox tails and bad terps acceptable in 2022?
