Nutrient Deficiencies Chart

[Stoner4Life]

I have one printed/laminated, it sits in the garden at all times.

N=nitrogen
P=phosphorus
K=potassium
Ca=calcium
S=sulfur (sulphur)
Mg=magnesium
Fe=iron
Mn=manganese
B=boron
Mb=molybdenum
Zn=zinc
Cu=copper

Make & keep a copy of this near your garden, address
the problems before they overcome the entire plant(s).

oh, BUMP

I am not bashing you but I wanted to let you know a few things that is wrong with that chart.........

ZINC (Zn)
White areas form at leaf tips and between veins. Occurs in alkaline soils. Zn deficiency can be treated by burying galvanized nails in the soil. Chemical fertilizer containing Zn can also be used.

Zinc is not white; they are yellow and they show yellow veins and follow the veins of the plant leaves.....

NITROGEN (N)
Pale plants, red stems, smaller growth. Rapid yellowing of lower leaves progressing up the plant. Add any chemical fertilizer containing N. Treated plants recover in about a week.

Nitrogen does not have red stems; cannabis natrually have red stems; but if stems are deep dark purple and just completely purple that is a different subject.... nitrogen can also start in the middle not just the lower part of the plant.......'

PHOSPHORUS (P)
Slow or stunted growth, red stems. Smaller leaves that are dark green. Lower leaves yellow and die. Add chemical fertilizer containing P. Affected leaves will not show recovery but new growth will apear normal.

Phosphorus does not show yellow leaves; they show brown spots with a dot in the middle and show random on the leaves but they are almost always in between the leaves veins and leaves to not die unless you do not fix the problem; but it has to be extremley severe for those leaves to die from a P issue.

POTASSIUM (K)
Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow. Add chemical fertilizer containing K.

Tall has nothing to do with a plant having potassium issues; it can affect any size plant; yes necrotic spots do appear on lower to middle leaves but the spots form on the leaves edges and but there can be yellowing following the spots but does not always have to be. Again red stems have nothing to do with potassium D.

CALCIUM (Ca)
Lack of calcium in the soil results in the soil becoming too acid. This leads to Mg or Fe deficiency or very slow stunted growth. Treat by foliar feeding with one teaspoon of dolomatic lime per quart of water until condition improves.

Have you ever tried foliar feeding with dolomite lime? Lime is very slow acting even if applied foliar and it's not meant for a foliar misting; you are better off putting it in the soil and leaving it there so you will add lime to your plant every time you water.

Nutrient Burn can be masked by a ton of things there is no 2 nutrient burn plants alike; mostly seedlings show tip burn where bigger plants can show many different signs of nutrient burn; in form of locking out nutrients to make it look like your not feeding enough; spotting; rusty looking leaves, crispy leaves; nutrient burn can mask so many things to make it look like it's not nutrient burn...... so you could go on all day talking about it with all the problems it causes.......

I am not trying to look like a know it all I just wanted to point out to you some of the mistakes that was in that chart.......

When using charts like these is what made me make a guide, because there is so much conflicting information and one problem you read can make it be like another and before you know it you are jumping back and forth throwing things at your plant trying to fix what you think is this problem and that problem.......which is why it needs to be in detail.

Stitch is our weed doctor, seriously.

In light of all the input above I've decided to dyke the post as now seen above.
There were some ideas such as the dolomitic lime that I had issues with as well. And although I did check the content for accuracy against other similar postings which seemed to be word for word in some of the deficiencies above I'll defer to your own homegrown abilities.......

what about purple stems that have gotten really stiff? Is stiffnes of the stems another sign of P deficiancy?



thanks

Dolomite lime takes up to a year to break down in soil and become active. Very slow acting.

Dolomite lime takes up to a year to break down in soil and become active. Very slow acting.

This is why it's best to lay lime in the Fall.

There is a very good thread on nutrition in my sig line... and of course, MynameStitch is an excellent resource also...
