Yellow lower leaves on 8-9 week old plants - Deficiency or age of plant?
Lower leaves are starting to yellow on some of the plants. I think I have corrected my cal/mag issues but now these yellow leaves. Going into week 9 of flower. Is this normal because of the age of the mature plant or a deficiency? Or is it still cal/mag deficiency?

Rust-colored margins and dots. I would like to go back to fertilizing but I am afraid that it is an excess of potassium
Outdoor in the vegetative phase, southern climate. Soil is Biobizz light mix. So far I have only fertilized 2 times with the tripack ph perfect Advanced Nutrients. These rust-colored burns are present on almost all older leaves. Enlighten me please 🙏

PH measuring for Organic Growers
If I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.

need exact details on making DIY egg shell fert, (how many eggs per how much water, dilute ratios, effective dose etc, using minimal eggs and vinegar.)
How many egg shells do I need to make an effective CAL fert? Are 6 shells soaked in 500ml of water with 1tsp of vinegar enough? What about if I boiled them in plain water? What is the dosage, ratio, and minimum amount of vinegar to use for this process, so it doesn't smell

Leaf burnt edges
One leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).
