I have a big problem. I added the epsom salts las week to my plant because it had a magnesium deficiency or at least thats what it looked like. But my plant has gotten worse. Could the yellowing le\ves be from lack of light by any chance, cos i know the canopy is pretty thick.But becaue the yellowing starts from the outside i don't think so. Also there are little brown streaks and cuts showing up on a few of the real yellow leaves. Could this be a calcium deficiency. I measure my ph before i ever add anything to the soil and its always in the 6's normally 6.4-6.6 so i don't think its lock out. I'm going home in a couple of days for a week and i don't wanna come back and finde her dead so i need all the help i can get quickly.

Looks like Mg judging by the way they yellow and the fact that the tips of the leaves veer a bit to the side.
Might take more than 1 feeding of Mg to straighten them out. Are you mixing the Epsom in a bit of hot water (till dissolved) before mixing it into the gallon?

I put it into warm water and shook so they shuld have been disolved. I only added 150ml of the mix( mix was 1L:1tsp of epsom salts) cos i had just watered them night before that. I added about 500mls more today. I' hoping this will help them.
Before i leave on thrursday shouldi flush the soil on wednesday and then add fresh nutes and water? Like i said if i haven't them fixed before i leave they will probably die so i reall wanna get it right!

The soil is wet cos i had just watered them thats when i noticed how yellow the leaves under the canopy were. I added epsom salts cos there was an almost definite looking mg defiiciencey and when i posted people agreed.

Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients - Taken from the OG grow faq.


The problem might not have been that Mg was absent but that another nutrient was too plentiful giving bad effects. Are you using tap water?

What is your soil PH? Make sure thats not off. To low if anything probably.
If your PH is good you need a shot, Use Epson salts 2 tbls per gal and that should take care of your problem. Do it once a month! Let your soil dry out tho first...she wont die or anything.
Definately Mg. I think if it were lockout it would be all over your leaves by now!

This would be 532 ppm magnesium. Normal curative rate is 120 to 240 ppm magnesium. This works out to be 1 to 2 teaspoons per 3.8 liters (1 gallon). Your going to get a potassium or calcium deficiency with that much mag your using.

Inject them with a dose of potassium nitrate stat. 3/4 teaspoon per gallon of water. This is the ingredient in some stump removers at hardware store like lowes and homedepot. Dexol, greenlight, spectricide are a few brands but there may be others... just check the label. This boost provides 400 ppm potassium. Also you may want to add 3/4 teaspoon powdered gypsum per gallon of water to provide 180 ppm calcium. Adding both of these will keep a balance between potassium, calcium, and magnesium. In the future, try to maintain a 4:2:1 ratio of k, ca, and mg. 1/4 teaspoon epsom salts per gallon of water is probably plenty if given on a constant basis to prevent mag def. 1 gallon =3.8 liters


Allow plants to get really dry between waterings. Water heavily when you do so that runoff occurs.

On a side note...I am pretty high.

Does the pot have holes on the bottom to vent the root and let water run off if not there getting to much fert and not enough air to the root let them dry out al the way between waterings and only feed once a week are you useing r.o. water or tap.and what kind of soil is that a pre mix or did you mix it? Try fox farm ocean forest you dont need to use fert.and if your going to keep growing in soil buy BOGs book Bonanza Of Green and you wont have these problems. www.fsbookco.com

eh, too much Mg, now you've got a zinc def caused by lockout. go get a good micro fert, flush the soil 3x the amount(ie 1gal soil 3 gal of water). then a light feeding the day after the flush.

regardless of how you want to fix it, there's too much mg causing a micro lockout, and the twist on the end of the leaf tips tells me it's zinc.

Sorry i have no interenet at my house and haven't been able to get access in a few days. I was told so many different measurements form 1/8 teaspoon of epsom salts to 2tsp per litre so i went for 1tsp. Okay it seems i'm doing a lot of things wrong. I checked my ferst the last day and they don't even mention zinc, my root juice has only 0.004% of it.

I'm flat broke so i leterally can't afford to but anything else for my plant. I plan to flush and then add fresh nute water and then leave them for a week(i'm not going to be around) this should give my plant plenty of time to recover uninterrupted.

Whoever said growing is easy was lying, it can be but not always. ,y other plant is haveing no prblems its just this fucker. But then again my other plant is two weeks younger so i didn't make as many mistakes.
