Ok, this is a chart i downloaded from an agricultural website and have been using it for several years now for diagnosing plant nutrient deficiencies. This chart is not about Mary Jane but instead a general description for vegetable crop type plants.
Understanding Soil Nutrients
NITROGEN
Soil Mobility
Nitrogen is not mobile in the Ammonium form (NH4+).
Nitrogen is very mobile in the Nitrate form (NO3-).
Plant Uptake
Plants absorb most of their nitrogen in the NH4+ and NO3- forms.
Functions in the Plant
Important constituent of the chlorophyll molecule.
Important constituent of amino acids, proteins, nucleotides, nucleic acids, amines and amides.
Deficiency Symptoms
Stunting of the plant.
Yellow appearance.
Chlorosis beginning at leaf tips and extending back along leaf blade.
Lower leaves show symptoms first.
Factors Effecting Deficiency
All crops except legumes require additional nitrogen beyond natural sources to
produce maximum yields.
Natural Supply Sources
Organic matters
Water (Irrigation and/or rainfall)
Livestock manures
PHOSPHOROUS
Soil Mobility
Mainly immobile, can move some in sandy soils.
Plant Uptake
H2PO4- on lower pH soils.
H2PH4-- on higher pH soils.
Function in Plant
Storage and transfer of energy obtained by photosynthesis and metabolism of
carbohydrates (ATP/ADP)
Essential component of coenzymes in plants which are involved in electron
transport reactions.
Integral part of plant reproductive system as a component of RNA/DNA.
Deficiency Symptoms
Purpling of lower leaves and stem on corn.
Corn ears will have uneven fill and curve at the tip.
Stunting.
Delayed maturity.
Soybeans and alfalfa may not show strong color effects but will redden lower
stem is P is extremely deficient. Both crops will exhibit stunting - forages will
have seedling development problems.
Factors Effecting Deficiency
Soil pH, greatest availability between 6.0 - 7.5.
PHOSPHOROUS - continued
Low CEC soils.
Soil microorganisms - more abundant in higher organic matter soils.
Natural Supply Source
Organic matter
Minerals
Absorbed phosphate
POTASSIUM
Soil Mobility
Potassium is somewhat mobile. More mobile on sandy or high organic matter
soils.
Plant Uptake
Potassium is taken up by the plant in K+ ions. Maximum demand by corn plants
for potassium is approximately 3 weeks prior to tasseling.
Functions in the Plant
Translocation of carbohydrates.
Starch synthesis (increases starch content in grain).
Activator of enzyme systems.
Plays important role in photosynthesis.
Regulates stomatal openings.
Necessary for normal lignin and cellulose development, which gives strength and
stiffness to plants.
Deficiency Symptoms
Marginal burn on leaves begins at the tip and extends back along margin.
Shows up on older leaves first.
May see poor brace root development,
Plants more prone to lodging.
Seeds and fruits shriveled.
Poor grain fill.
Legumes may die off.
Factors Effecting Deficiency
Lack of soil moisture.
Water logged soils.
Low pH soils.
Recently limed soils (calcium has been shown to compete with K+).
Natural Supply Sources
Disintegration and decomposition of rocks containing potassium-bearing
minerals.
CALCIUM
Soil Mobility
Held fairly tight to soil colloids, but will leach out of topsoils in light textured,
well drained soils.
Plant Uptake
Ca++ exchangeable form. Absorbed from soil solution and also adsorbed off of
soil colloid surfaces.
Functions in Plant
Necessary for cell elongation and normal cell division.
Protein synthesis.
Affects permeability of membranes.
Important in the formation and functioning of root nodule bacteria.
Also important role in soil texture by aggregating colloidal clay and humus particles.
Deficiency Symptoms
Seldom encountered in row crops.
CALCIUM - continued
Uniform chlorosis that appears first on young leaves.
Retarded growth of terminal bud.
Grass crops - leaves fail to unroll.
Stunted roots.
Factors Effecting Deficiency
Coarse textured sandy soils with low CEC and low pHs.
Conditions impairing the root growth will reduce uptake of Ca.
Natural Supply Source
Different types of minerals, such as feldspars, amphibole, pyroxene, dolomite,
calcite, apatite and gypsum.
MAGNESIUM
Soil Mobility
Does not leach readily from soil, held on surface of clay and organic matter
particles.
Plant Uptake
Mg++, mass flow mainly, root interception lesser extent.
Function in Plant
Most important role is the formation of chlorophyll.
Aids in formation of many plant compounds, such as sugars, proteins, oils and fat.
Regulates uptake of other plant nutrients, especially phosphorous.
Involved in the translocation and metabolism of carbohydrates.
Deficiency Symptoms
Interveinal chlorosis of lower leaves starting at leaf margins and progressing
inward. As deficiency becomes severe the leaves turn reddish purple.
Symptoms occur most frequently in small plants.
Severe deficiency causes stunting.
Factors Effecting Deficiency
Acid sandy soils.
Organic soils containing free calcium carbonate.
Soils with very high available potassium.
Continued liming with calcitic limestone (low Mg content).
Natural Supply Source
Weathering of minerals.
SULFUR

Sulfur is very mobile in the soil.
Plant Uptake
Sulfur (S2) is oxidized, sulfofication to form available sulfate (SO4--).
Functions in the Plant
Constituent of three amino acids found in plant proteins.
Component of glycosides involved in respiration.
Nodule formation in legumes.
Oil synthesis (soybean, sunflower).
Deficiency Symptoms
Stunting of plant.
Plants will have a light green color (resembles nitrogen deficiency).
Chlorosis may occur on the entire plant.
Corn may have striping of upper leaves (mostly young plants).
Legume plants (alfalfa) will have long and slender leaves.
Alfalfa plants will not branch normally resulting in a thin stand and delayed
maturity.
Factors Effecting Deficiency
SULFUR - continued
Sandy soils.
Low organic matter soils.
Rain or irrigation water low in sulfur.
Natural Supply Source
Organic matter is the primary source.
ZINC
Soil Mobility
Immobile.
Plant Uptake
Zn++, diffusion on soil solution.
Functions in Plant
Component of several respiratory enzymes and other enzymes.
Forms covalent bonds with nitrogen and sulfur.
Influence electron transfer reactions subsequently on energy production in plant.
Deficiency Symptoms

Soybeans
Appears very early in plant growth.
Yellowing between the veins.
Eventually entire leaves and stalks become yellow and almost white.
Eventually leads to loss of chlorophyll in the veins.
Factors Effecting Deficiency

no problem! Been seeing a bunch of deficiency threads so figured it was time to educate. While the write up was intended for vegetable crops, the symptoms and cures are relatively close to our Herbs. As well as a little educational info on how these nutrients work and how they are obtained by the plants.
Enjoy!

Really simple way to grow plants in soil, is to do a soil / coco mix and feed them like it's hydroponics; every 3 days. Water as needed in between the feedings. Really simple, with excellent results.
Pretty hard to screw it up too. You have to be super aggressive with feedings to mess it up. As long as you stick to only feeding every 3 days, you have to be pretty nuts mixing your nutrients to overfeed.

Can't forget about nutrient antagonism. http://www.totalgro.com/concepts.htm
This is why I can't understand cannabis specific fertilizer giving backward ratio's .. 0-5-5 for example.
Letting your leaves die during flowering is just one of the internet fallacies. Leaves produce bud!
Dyna-Gro is the only product I've seen offer all 16 essentials elements in one bottle. Generally if it's a "canna" food, it's a gimmick.

Worm casting are great. But as I stated in the other thread, it needs to be used in conjunction with other nutrients.
