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.
Pictures 1-2 shows calcium deficiencies. First one shows late, 2nd one shows early development. http://www.icmag.com/ic/showthread.php?t=11688 just scroll down to the Calcium section. stitch she done a surpurb job putting this together started over at overgrow when it was up, she finished it here at icmag

This was compiled by some smart fellas.Take not how excess calcium locks out magnesium and binds with phosphorous rendering it less effective.Highly calcified tapwater is the cause of many problems.http://www.ces.ncsu.edu/depts/hort/consumer/quickref/fertilizer/nutri_def.html
