Plant abuse chart

If dust fell out it sounds like pollen. Any pics? Hopefully it did not pollinate the others but if it was balls on a female then its hermie and not great for smoking anyway.

hey yeah i just started growing and well obviously i am inexperienced but i have my plant in a maxwell coffe can near the window and sometimes i put it under a flourescent light and switch it back over to the window when it is sunny, but hear is my question is it possible to take a leaf off and smoke it, not killing the plant, it looks to be an adolescent possibly a teen but like i said i just started and it is my first plant and plan to learn from my mistakes the first time and do better the second but can i smoke some leafs without killing it....

Last night I decided to start using my 1000w hps instead of the CFL's I was using. When I did this I put my floor fans next to the plants to keep them cool. This morning I woke up and a few of my plants had brown spots on them. Well, the fan that I am using has a ozone generator in it that I had been using for the smell. Because of the pics from this post I realized that that was the problem. Thanks so much, I am sure you saved me a ton of head scratching.

Never had heard that ozone could harm plants.

Yo man you can take a leaf or two off to smoke it but, it won't get you very high if at all. To get buds the plant needs 12 hours day and 12 hours of pitch black, uninterrupted dark. Then it will get buds which are smokeable.

Yes ozone in high concentrations can cause spots i.e damage. I however use ozone and even in a sealed closet [at one time] I was never able to get the concentration high enough to do any damage. Doesn't mean its impossible its just very rare.

ELEMENT and Description of Deficiency and Toxicity

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, petioles 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 apical meristems 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.

Turned the ionizer part of my fan off yesterday and this morning the leaves have almost healed themselves completely. I noticed that they have only grown about .5 inch over the last 24 as opposed to the 1-1.5 that they were growing per day. I attribute this to the healing of the leaves. But, I am super stoked that that is what it was. Easy fix.

Is it ok to use the PH up and PH down they sell in pet stores for aquariums?

And one question, is it ok to use diluted vinegar to lower PH?

Only ok in soil not hydro.

[kush4yeild]

if you been runin on 7 i would even go a bit lower for a few feed have your leafs gone a pail yellow on new shoots

[shadygrowshow]

lemon juice is great to bring down ph my tap water has a ph of 7+ and i lower it with lemon juice works great just buy a bottle from the supermarket

yea vinegar is cool ive used it!i use soil

[luv13ug]

very helpful!

I figured out my "yellow fever" problem lol

[waterbong]

i also read that dried coffee grounds are ph nuetral and will actually bring the levels down. has any on done this?? i've added them to a couple of my plants they healthier and alot greener..

[popwarfour]

the spelling... hahah to funny

[homegrown410]

hey, i could really use some help on figuring out the problem of my three plants that i have in DWC buckets, each plant is showing the same symptoms, just a little wilted look on the old lower leaves with the top 1/3 looking healthy, pic included of one of the large fan leaves. I have looked through the plant sickness charts and nothin really jumped out at me that matched, might be a kind of mold but this would be my first time, humidity is always 50 to 60%. I would appreciate all advice, Thanks
