by the way,,,
by the way,,,its just random mid grade bag seed. could this be the problem? i grew out some nice skunk plants before this! nice fat colas,,and no problems ! i did have 2 nice ones make it to about 35-40 days of 12/12 and just do this till it got worse and worse and then BAM !! death became them,,it was very sad.

Ammonia toxicity/calcium deficiency.
Ammonia toxicity/calcium deficiency.
Ammonia and urea are toxic to plants in large amounts. It cannot be stored in the plant safely. Miracle grow is 100% ammonia or urea.
When ammonia becomes toxic, it can resemble calcium deficiency. It disrupts calcium function in the plant.
Miracle grow plant food lacks calcium, magnesium, and sulfur.
Plants require nitrogen, phosphorus, potassium, sulfur, calcium, and magnesium in large quantities. They also need small amounts (called micronutrients) of iron, manganese, zinc, copper, boron, and molybdenum.
If you mix powdered/pulverized (not pelletized) dolomite lime into your soil mix, this will give the plants calcium and magnesium. Ideally, you should test different lime rates with your soil mix. Using 3 seperate containers, add 1, 2, and 3 teaspoons lime per gallon of mix. Wet well. Wait a week. Mix 1/4 cup soil mix with 1/4 cup distilled water. Stir. Wait 30 minutes. Test this slurry ph. Pick the best lime rate. Just guessing, try 2 teaspoons per gallon of mix. Be sure to mix the lime well with the soil...it needs to be uniform.
If you forgot to add lime, you can surface apply it and water in. Try 1 1/5 teaspoons per gallon of soil mix. You can only do this if ph is low!!!
If your ph is ok or on the high side, you can add cal mag to your water by using 1/4 teaspoon of both epsom salts and powdered gypsum (per gallon of water) along with the regular ferts. Easily disolvable gypsum you might find at a brew your own beer/wine store. Organic traditions brand will not disolve. Epsom salts you can find at the drugstore. Calcium nitrate can be used instead of gypsum at the same rate. Calcium chloride can be used also instead of gypsum. You might find it in bottles sold under names like blossom end rot stopper for tomatoes. It will take the % calcium and net weight of the bottle to tell you how much to add 60 ppm ca. Both calcium nitrate and calcium chloride are easier to disolve.
You can find a nitrogen, phosphorus, potassium fert containing the 6 micronutrients. It should contain little urea or ammonia nitrogen and the rest nitrate nitrogen. Avoid ferts with potassium chloride. Somebody mentioned finding a 20-10-20 fert at Lowes fitting this description. You add this to your water. At bloom, you might switch to something like Peters/Jacks classic 10-30-20. It has all the micros and has not so much ammonia or urea nitrogen. Surprisingly, 20-10-20 will work ok for both bloom and growing.
Only thing left to add to your water would be sulfur. Occassionally not always add 1/4 teaspoon per gallon of water epsom salts from the drugstore along with the regular fert. (if your constantly adding the low rate of cal mag in your water described before, your already adding epsom containing sulfur) An alternative to this would be to mix 3/4 teaspoon powdered gypsum per gallon of soil mix at planting time along with the lime. In this instance, organic traditions brand is ok.
Ph is very important. At least get some ph test strips from the aquarium section of a petstore or brew your own beer/wine store. You can use them to test the soil ph sometimes and adjust the ph of the fert water everytime after adding the ferts.
How to test soil ph: After watering/ferting well. Wait 30 minutes. Then apply some distilled water to the pot surface till 1 or 2 ounces of runoff occurs. Catch on a saucer. Test ph. If you can tilt the pot after watering/ferting and waiting 30 minutes and get some liquid out, you can test that instead.

BV,,thank-you. i very much appreciate it.guess im going shopping ! so basically,,i just make a water mixture with all the right stuff(depending on ph)and water ?because,,mir gro. doesnt have what is needed to grow .and too much of what isnt. i think i got it now,,,,im going to put this info. to use and hopefully it will straiten them out. thanks again,,and ill keep you posted. will these plants continue on to maturity? two already died.

First thing you should do is flush the soil with plain water. If the miracle grow soil advertises it lasts 3 months this won't work well and transplanting into a more friendly soil may be your only option.
Supplies shouldn't cost too much. Maybe $30...
Suggestions to have handy:
--high nitrate nitrogen fertilizer with little ammonia/urea and containing all 6 micronutrients
--pulverized dolomite lime
--epsom salts
--ph test strips
--gallon of distilled water
--powdered gypsum (from a brew your own beer wine store)
--bag of perlite
Feed with every watering but weakly. Make sure you get alot of runoff everytime.

what am i doing with the perlite? i had 2 of them in a perlite vermiculite mix to see how they would grow,,and thought maybe they were not getting any nutrients or enough being out of soil,,,and i put them back in it .i didnt know if that could be the problem,,,at the time.i have perlite and vermiculite still,,,should i put the sick ones back in that? or should i put them in a diff. soil altogether? or do i flush them real good and just add those nutes?sorry about all the questions,,,but this all has been driving me nuts ! thanks !
i had 2 of them in a perlite vermiculite mix <----- this is a soiless medium and should have water PH'd to 5.8-6.2. to flush your soil take 3x water per container for instance a 1 gal container should have 3 gal's of properly PH'd water ran through. dont fert every watering unless your in hydro coco or perlite vermiculite mix as mentioned before MG soil lacks micro and macro nutrients if you use this soil you should add the micro/macro nutes to soil. but your FFOF soil should give ya better results, because your haven problems i would start FFTB at 1/4-1/2 strength dossage if plant likes it continue. each wk up the dossage untill full dossage or what plant can handel is achieved.

Have you tested soil ph? You only add dolomite lime to the top of the pot if the ph is low!!! Add cal mag in your water along with the tiger bloom if ph is ok or high. Calcium will help the plants recover from toxicity. Take time to carefully reread the previous suggestions I gave.lotatokin said:
