[Ennui42o]

There were several posts, faqs, etc concerning nutrient deficiencies at OG but there was one that, for me, soared above the rest. It was very simple and helpful; it was in actual chart form with the descriptions of sick plants (i.e. yellowing leaves) and various symptoms listed on the vertical columns, In the top horizontal rows all the macro and micro nutes were listed. Then in each row/column in the chart there was a simple yes or no listed to inform the reader what deficiency corresponded with the symptoms he or she was having. Even though some problems might have two nutrients listed as possible culprits, it was nice to quickly narrow the problem down to a handful of nutrients or lack thereof.

My question here is; does anyone have a copy of this guide? It was extremely useful and like I said very quick and concise. I think I have it printed out somewhere but I am not sure if I will be able to find it. Like the strain guide that was recently posted here, I feel this guide is essential OG material and it would be awesome to be able to put it back up for all to use.

If I can find my copy, I will scan and upload it providing that the mods have no objections. But if anyone has the guide saved to disk It would be great to post it or make a sticky in the sick plants forum. Or at the very least PM me and e-mail me a copy so I can put it with my other info.

Any help would be greatly appreciated. Sorry for the long-winded post.

Peace,
E.

Try www.cannaworld.com and look on the left of the page for OG guides,it's there

all the pics in the abuse chart are still linked to OG and won't pop up

Damm Ill shut the hell up about my ebook soon .... but I have the 3 major and different plant trouble documents from overgrow.



These i did take the time to quickly merge into one document but for honors stake I added the separate original documents. Just with the one you have links that allow movement around the different problems.



Ahh well just a FYI.. slap me when I start getting annoying...

[shithappens]

Sorry located the one I figgured you where talking about and found that it wasnt included in the ebook but will be in the next issue...

After my last post I wasnt gunna say just wait so I included it here

Sorry about the table but hell how do you do tables in here????


Quick List Symptoms of nutrient deficiencies

This is a chart showing some common symptoms of nutrient deficiency and over fertilization. Always remember that you never want to over compensate for any deficiency because of the risk of over fertilization. Use caution when adjusting the strength of the nutrient solution. Deficiencies may also be attributed to a solution is too acidic or too alkaline so pay close attention to your pH. In order for all elements to be readily available to the plant the pH should stay in the range of 6.5.

Click Here for a list of elements along with their signs of deficiency and toxicity.





Use this chart as a reference ONLY. This is not a guaranteed diagnosis of your plant and you should only use this as a guideline to help you figure out what your nutrient solution is lacking...

N Nitrogen:

Deficiency: Plants will exhibit lack of vigor as older leaves become yellow (chlorotic) from lack of chlorophyll. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.
Toxicity: Leaves are often dark green and in the early stages abundant with foliage. If excess is severe, leaves will dry and begin to fall off. Root system will remain under developed or deteriorate after time. Fruit and flower set will be inhibited or deformed.

P Phosphorus:

Deficiency: Plants are stunted and older leaves often dark dull green in color. Stems and leafstalk may turn purple. Plant maturity is often delayed.
Toxicity: This condition is rare and usually buffered by pH limitations. Excess phosphorus can interfere with the availability of copper and zinc.

K Potassium:

Deficiency: Older leaves are initially chlorotic but soon develop dark necrotic lesions (dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken.
Toxicity: Usually not absorbed excessively by plants. Excess potassium can aggravate the uptake of magnesium, manganese, zinc and iron.

S Sulfur:

Deficiency: The initial symptoms are the yellowing of the entire leaf including veins usually starting with the younger leaves. Leaf tips may yellow and curl downward.
Toxicity: Leaf size will be reduced and overall growth will be stunted. Leaves yellowing or scorched at edges.

Mg Magnesium:

Deficiency: The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins.
Toxicity: Magnesium toxicity are rare and not generally exhibited visibly.

Ca Calcium:

Deficiency: Young leaves are affected first and become small and distorted or chlorotic with irregular margins, spotting or necrotic areas. Bud development is inhibited and roots may be underdeveloped or die back. Fruit may be stunted or deformed.
Toxicity: Difficult to distinguish visually. May precipitate with sulfur in solution and cause clouding or residue in tank.

Fe Iron:

Deficiency: Pronounced interveinal chlorosis similar to that cased by magnesium deficiency but on the younger leaves.
Toxicity: Excess accumulation is rare but could cause bronzing or tiny brown spots on leaf surface.

Mn Manganese:

Deficiency: Interveinal chlorosis on younger or older leaves followed by necrotic lesions or leaf shedding. Restricted growth and failure to mature normally can also result.
Toxicity: Chlorosis, or blotchy leaf tissue due to insufficient chlorophyll synthesis. Growth rate will slow and vigor will decline.

Cl Chlorine:

Deficiency: Wilted chlorotic leaves become bronze in color. Roots become stunted and thickened near tips.
Toxicity: Burning of leaf tip or margins. Bronzing, yellowing and leaf splitting. Reduced leaf size and lower growth rate.

B Boron:

Deficiency: Stem and root tips often die. Root tips often become swollen and discolored. Internal tissues may rot and become host to fungal disease. Leaves show various symptoms which include drying, thickening, distorting, wilting, and chlorotic or necrotic spotting.
Toxicity: Yellowing of leaf tip followed by necrosis of the leaves beginning at tips or margins and progressing inward. Some plants are especially sensitive to boron accumulation.

Zn Zinc:

Deficiency: Chlorosis may accompany reduction of leaf size and a shortening between internodes. Leaf margins are often distorted or wrinkled.
Toxicity: Zinc in excess is extremely toxic and will cause rapid death. Excess zinc interferes with iron causing chlorosis from iron deficiency.

Cu Copper:

Deficiency: Young leaves often become dark green and twisted. They may die back or just exhibit necrotic spots. Growth and yield will be deficient as well.
Toxicity: Reduced growth followed by symptoms of iron chlorosis, stunting, reduced branching, abnormal darkening and thickening of roots. This element is essential but extremely toxic in excess.

Mo Molybdenum:

Deficiency: Often interveinal chlorosis which occurs first on older leaves, then progressing to the entire plant. Developing severely twisted younger leaves which eventually die.
Toxicity: Excess may cause discoloration of leaves depending on plant species. This condition is rare but could occur from accumulation by continuous application. Used by the plant in very small quantities.
