hows it going, I have a boggelgum that has become a magnesium hungrey little slut since I flipped her to 12/12, I got some epsom salt, as I know its the solution to this particular problem, but I dont know how much to use, the kind I got says 495 mg per teaspoon? My deficency has worked its way about half way up the plant, so i think it needs a healthy dose, any how, suggestions?

You'll want to add the epsom salts with EVERY watering now until the end of flowering. Initially, I would put 1 teaspoon per gallon for the first few waterings and then back off to 1/4-1/2 teaspoon per gallon the rest of the way. Also, and this is very important, you'll want to dissolve the epsom salts in a cup of very hot water before adding it to your nute solution. Otherwise, the salts won't dissolve and the plants won't be able to take them up. Good luck!

Excellent post Rellikebuzz, very good info

Magnesium (Mg) - Micronutrient and Mobile Element


Magnesium helps supports healthy veins while keeping a healthy leaf production and its structure. Magnesium is significant for chlorophyll-production and enzyme break downs. Magnesium which must be present in relatively large quantities for the plant to survive, but yet not to much to where it will cause the plant to show a toxicity.


Magnesium is one of the easiest deficiencies to tell… the green veins along with the yellowness of the entire surrounding leave is a dead giveaway, but sometimes that’s not always the case here. In case you have one of those where it doesn’t show the green veins, sometimes leaf tips and edges may discolor and curl upward. The growing tips can turn lime green when the deficiency progresses to the top of the plant. The edges will feel like dry and crispy and usually affects the lower leaves in younger plants, then will affect the middle to upper half when it gets older, but It can also happen on older leaves as well. The deficiency will start at the tip then will take over the entire outer left and right sides of the leaves. The inner part will be yellow and or brownish in color, followed by leaves falling without withering. The tips can also twist and turn as well as curving upwards as if you curl your tongues.


Excessive levels of magnesium in your plants will exhibit a buildup of toxic salts that will kill the leaves and lock out other nutrients like Calcium (Ca). Mg can get locked out by having too much Calcium, Chlorine or ammonium in your soil/water.
One of the worst problems a person can have is a magnesium def caused by a ph lockout. By giving it more magnesium to cure the problem when you are thinking you are doing good, but actually you are doing more harm then good. When the plants can’t take in a nutrient because of the ph being off for that element, the plant will not absorb it but it will be in the soil… therefore causing a buildup. A buildup will be noticed by the outer parts of the plant becoming whitish and or a yellowish color. The tips and part way in on the inner leaves will die and feel like glass. Parts affected by Magnesium deficiency are: space between the veins (Interveinal) of older leaves; may begin around interior perimeter of leaf.




Problems with Magnesium being locked out by PH troubles

Light Acid Soils, soils with excessive potassium, calcium and or phosphorus


Soil

Magnesium gets locked out of soil growing at ph levels of 2.0-6.4
Magnesium 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 Magnesium deficiency.



Hydro and Soil less Mediums

Magnesium gets locked out of Hydro and Soil less Mediums at ph levels of 2.0-5.7
Magnesium is absorbed best in Hydro and Soil less Mediums at ph levels of 5.8-9.1
(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 Magnesium deficiency.



Solution to fixing a Magnesium deficiency
Any Chemical/Organic nutrients that have Magnesium in them will fix a Magnesium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Other nutrients that have magnesium in them are: Epsom salts, which is fast absorption. Dolomite lime and or garden lime (same thing just called different) which is slow absorption. Sulfate of Potash, Magnesia which is medium absorption. Worm Castings, which is slow absorption. Crabshell which is slow absorption. Earth Juice Mircoblast, which is fast acting. (a must buy!! Has lots of 2ndary nutrients).
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.


Here is a few pics of what a magnesium deficiency looks like in different stages. First one was on my plant at an early stage of veg. growth. This was the start of a very early magnesium deficiency. and the last one is from what magnesium lockout looks like when it is caused by a ph problem.

hey guys i did this last week so watch it......

to much mg................ o no.......

i use AN cal mag...... i have used it so much that i now just poor a lil in the rez as the weeks go by... well 3 nights ago i poored n sliped dumped a lil to much....
i said fuck it more mg dont hurt.
boy was i wrong.... it make a nute lock out just like a mg dif.... so watch your self.... it did not kill my clones but it sure stunted them.....

pull the 12 & putting them back in the cloner for a few day n added new one's....

I thought this sounded like my friend Stitch,
and yep,, it sure is,, pay attention,, Stitch knows what's what.
BOG brought Stitch here for that very reason.

Take care........................ "iron"

Epsom with every watering in flower? Sounds a little overkill. I hardly use any of the stuff and do just fine.

it would depind on a lot of thing's

sume plants cant get enuff & some can......

water makes a big deal! my tap water need's a lil more mg then any of my other grow's in a town north of me.....
if your using r/o i dont see where u would use that much but sum for sure .
i would think the same for soil as to dro but thats a thought im not a soil grower....

i know grape ape lov's cal/mg

DOH! ya always measure before you dump shit in your rez lol. I dont know shit about hydroponics other than that!

thats the only thing that i do that with.....neva again..... i member i was in a hurry as well but o well at lest it was baby clones and i have more plus thell live...

everything else is down to a tee bro with AN theres no give when u use the whole line....
