deficiency issue in my flower box

[vegasguy911]

i cant figure it out i think its a mag def, but the leaves are getting little dead spots all over them like litterally circular spots of brown dead area, they look good aside from that. ive tried some epsom salts maybe thatwill help, cant get pics any suggestions.>???

from your description in the PM it sounds like your experincing this


Calcium (Ca) -Macro Nutrient and an Immobile element.

Calcium is another important element that helps the plants cell walls, cell division in making the plants stems, stalks, branches stronger, as well as contributing to root growth, mostly the newer root hairs, Calcium also helps enhancing the uptake of K in the the plants roots. Calcium moves really slow within the plant and tends to concentrate in roots and older growth.



When plants exhibit a Calcium deficiency the younger leaves are the first to show it as well as older leaves. The Leaf tips will die back, the tips may curl, and growth of the plant is stunted. The plant can show a weakness in the stems and branches, as well as a under developed root system that can lead to bacteria problems with roots dieing off. Having slow plant transpiration rates can aggravate the uptake of calcium. Make sure your soil isn’t very acidic, for calcium gets harder to be absorbed through acidic soils, Which leads to having a plant that is deficient in Calcium. The leaf tips, edges and new growth will or may turn a yellow/brown color that happen in spots and often surrounded by a sharp brown outlined edge and then the leaf tips die back. If too much calcium is given at an early stage of growth it can stunt the growth of your plants. Having to much of calcium will also flocculate when a concentrated form is combined with potassium. The parts affected by a calcium deficiency are the roots. Stem or petiole, young or old leaves.

Too much Calcium will lead to other micronutrient deficiencies. Calcium fixation is caused by many types of mediums such as: clay soils, unbuffered coco and humus. The lime tends to bond to these soils very easily. The stems of the plant will not be able to hold the plant up and will exhibit a white brown in between the veins of the leaves when having too much calcium. Also having to much potassium and or nitrogen will cause a calcium lockout.



Problems with Calcium being locked out by PH troubles

Very acidic soils with excessive potassium, dry and or wet soil. Lack of calcium in the soil may cause too acidic soil. This may cause to Mg or Iron deficiency or very slow stunted growth


Soil


Calcium gets locked out of soil growing at ph levels of 2.0- 6.4
Calcium is absorbed best in soil at a ph level of 6.5-9.1 (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a
Calcium Deficiency.


Hydro and Soil less Mediums

Calcium gets locked out of Hydro and Soil less Mediums at ph levels of 2.0- 5.3
Calcium is absorbed best in Hydro and Soil less Mediums at ph levels of 5.4-5.8 (Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Calcium Deficiency.




Solution to fixing a Calcium deficiency
To fix a calcium deficiency you can treat by foliar feeding with one teaspoon of dolomite lime or Garden lime per quart of water, Or Any Chemical/Organic nutrients that have Calcium in them will fix a Calcium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Or you can take crushed up dolomite lime or garden lime in a gallon of water and water it in the soil. 1 to 2 teaspoons per gallon of water, which will be slow acting. Garden Gypsum, which is medium absorption. Limestone, which is medium absorption, Rock Phosphate and Animal wastes which are both medium/slow absorption. Note: Caution when using gypsum to an already acid soil (pH that is less than 5.5) can have a very bad effect on different types of plants by effecting the absorption of soil aluminum, which is poison to plant roots.


Now if you added to much chemical nutrients and or organics, (which is hard to burn your plants when using organics) you need to flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients. excert taken from stitchs tutorial in the infirmary http://www.icmag.com/ic/showthread.php?t=11688 just scroll down to the Calcium part it has pics you can also hit her link in my sig sick plants very very good work and took her long time to put together.

yeah im gonna flush ,but both exhibited it but the one on the right is getting really bad, im using fox farm ocean forest mix,and lately yeah tap water im gonna just use distiled tell i finish them off. this is the first time ive used FFOFM and to tell you the truth i have never had a problem like this with just regular perfect mix bought from wall mart, but even though the leaves are looking like shit the buds on the left one are definately the best ive ever grown, im not sure if its the soil or the care ive taken in doing this scrog right but they look good, the ****ed up part is they are both seeds grown from the same batch of g-13 diesel Xmango widow, and one is awesome and finishing up and the pistils are getting red and its nice and trichy, and the problem with the brown spots (literaly like random brown pokodots but definatly not a pest), have cleared up and the one on the right has gotten worse and the bud growth is almost half as much and it is trichy but the spots are spreading so much im worried if it will be ok.

when using city tap water remember most large citys use cloriene to sanitize the drinking water i use tap water thats treated. i have jugs full and open to allow cloriene to evaporate over night is usally good enough but rule of thumb is to allow 24 hrs open before use. this could be 1 of your culprits that lead to your current problem, whats your water PH when you water ???
