Thank you very much to my old buddy OnlyOnamental for this fine bit of work, where ever you are, I hope you are well!
First Aid for plants:
Salt stress (over-fertilisation, drought, heat), nutrient lockout (over-watering too?), and pests.
Low Ascorbyl palmitate/Vit. C: General first aid, many beneficial effects, antioxidant and plant defence, regenerates roots, ascorbyl palmitate: Surfactant, optimal in combination with lecithin.
Aspartate resp. malic acid: Metabolites trigger plant immunity and stress responses, energy, and reductive equivalents.
Malic acid works against aluminium toxicity.
Choline chloride: Enhanced photosynthesis, glycine betaine precursor
Citric acid & trehalose (foliar), honey (roots): Osmoprotectants, complexation of minerals and quick energy
Cysteine or N-acetylcysteine: Antioxidant and UV-protectant, recycling of methionine, sulphur & nitrogen fertiliser, glutathione precursor
Ethanol: Inhibits PLD and senescence
Glutamic acid & low glycolic acid: Nitrogen fertiliser, synergistic photorespiration intermediates, oxidative defence, penetration enhancer, glutathione precursor
Glycerol: Humectant, resorption accelerator for foliar spray, important in SAR and ISR, reduces free phosphate (higher concentrations under phosphate toxicity)
Glycine: Chelator and nitrogen fertiliser, glutathione precursor
Glycine betaine: Osmoprotectant
myo-Inositol: Helps for phosphate storage, osmoprotectant
alpha-Ketoglutarate: Against nitrogen over-fertilisation and nitrate and ammonia toxicity
Magnesium, calcium, potassium: pH adjustment & because it’s always good and often deficient?
As magnesium bisglycinate, calcium citrate, potassium silicate
Low methanol/formic acid: Increases plant growth, preservative, C1 donor
Ornithine & proline: Nitrogen fertilisers, osmoprotectant, humectant & resorption enhancer
Phenylalanine: Phenylpropanoid precursor, plant immune defence
Potassium silicate/diatomaceous earth: Plant protectant, mild insecticide
Trehalose: protectant against salt stress and drought
Vitamin B complex: Vitality, boosts roots, ethylene synthesis
