Solution for 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 affecting 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.
The first one is Calcium.The other two look like Molybdenum deficiency. Solution to fixing a Molybdenum deficiency One way to fix a Molybdenum deficiency is to foliar spray with Molybdenum, like Miracle Grow All Purpose plant food and Miracle Grow: Tomato Plant Food. These can also be used to mix in with water as well. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)Other nutrients that have Molybdenum in them are: I think Peters All Purpose Plant food does, as well as Greensand, Lime. Green sand and lime is slow/medium absorption, while Peters All Purpose Plant Food is fast absorption.
