Calcium Problem

Ok, I used some week old foxfarm 3/2-BB/TB on two of my ladies. They both seem to have developed a calcium problem, unless its a fungus im not aware of. I got some dolomite lime, but my question is what amount should be used in 1 gallon of water? How much should I use? I saw somewhere its based off the pot size which is 3 gallons. How long will it take to show a response? Will the leaves heal or stay the same?

Usually you mix the lime into the soil, and i would usually do about a cup per pot of soil. I would just sprinkle it over the top of the soil, and then feed normally. You may also want to get some Green Stay, which is calcium, mg, iron, and nitrogen, it will green everything right up. 1tsp per quart, then foliar it on.

CalMag helps for fast uptake. pH? I use a heaping Tbsp dolomite per gallon of soil when mixing soil.

these questions a bit out of everyones league?
errr no.....................................................

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.

Kinda does, Ive read through the troubleshoot guide and problem is theres different answers everywhere you look. Even in the garden saver manual, theyre vague on dosing and mixing amounts. Like above, it actually has two different answers. 1tsp/quart with foliage feed or 1-2tsp/gallon to soil. I recall you dont want to foliar feed during flowering due to mold. Already did the 1tsp/gallon but i still need to know HOW MUCH to use one them. The whole gallon to one plant or a proportion? So far theyve both got 1L of it. Still need to see if anybody can tell me how long it takes to show any effect of working.

Already started removing them. The one with the upcurled leaves has for the most part been stripped but I wasnt sure to what extent they should be removed. So is it pretty much everything thats been affected?
You're doing the right thing. The rule is that if the leaf is more than 50% damaged then remove it as it is a waste of the plants energy and will not repair properly. This also allows you to concentrate on the new growth rather than the dying matter.

Good luck !

Alright, came home from work and theyre all doing alot better. after stripping most of the damaged leaves all newer growth shows no signs of spreading so I think Im clear. Thanks to all who put in some good advice. +rep to ya
