Relax. Magnesium want hurt the plant. Can't ever really get a toxicity. I was hoping to test out a few leaves with different spray rates and no drench. Science. Now you know that you need to add additional magnesium with your fertilizer because it is so high in potassium and your source water may contain a lot of calcium. Like I said before, a mag def will be hard to correct you plant is so far along. But might as well try. Magnesium deficiency can have a serious impact on plant growth not only for its role in the chlorophyll molecule but also helping reactions in the plant speed up (enzyme activator). I bet future crops will be even better since we discovered a flaw in the ferts. :smoker:

Your plant although yellowing a bit doesn't look like it's in mortal danger. She's going to make it so while it is good to take care of any problems that might arise you really don't have to worry excessively. You've only got weeks to go and the plant looks in no immenant danger. It definitely won't hurt to try the epsom salts but don't trip out no matter what, your buds are going to be fine. Some yellowing of lower leafs is natural as plants mature and some strains are more susceptable to that. It won't be long until you have this grow under your belt and kind buds to smoke and by the way for a first grow it looks very nice, you are doing a fine job. Keep on rocking!

Once a Mg deficiency occurs, it is very difficult to correct, particularly if the deficiency occurs during the mid-point in the growing season.
You know to add 1/4 teaspoon (1.25ml) epsom salts per gallon (3.8L) of water along with the Canna flores from now on. :canabis:

Since you drenched and sprayed with the extra magnesium, I don't think I would add any more extra regularly for this crop/these particular plants. But in the future, add that 1/4 teaspoon per gallon in the water everytime you use the Canna flores. If you want, test 1/8 teaspoon and 1/4 teaspoon and report your findings in future crops to see which rate worked better.

aHa! 2 gallons for an almost 6 feet plant while 3 gallons root space is recommended for plants of that size (1/2 gallon per foot is the rule). I think that's the reason for the premature yellowing of the fan leaves

dude, no offense, im here to help by all means i never flame anyone who asks for help. please dont take this wrong by any way..... but that is the worst case of a magniseum deficiency i have ever seen.........

how did you let it get that bad? your fert must have like no magniseum in it, your plants dont look like its getting enough, plants that suck there leaves dry leave a different brown tone to the leaves when they die, its like the plant sucks it and dies naturally like the corn plant does when it sucks all the nitrogen from its leaves

but ph issues when the leaves die prematurely, there colors of the leaves are a different brown color, more of a darker brown and different hues sometimes, but in this case you just are not getting enough magnesium,

have you given them any epsom salts or anything with magniseum?


o ...with no tools to measure i woz thinking to add distilled water witch i did for 2 waterings...then they toke a turn for the wurst.....so i stopt giving that distilled water....2 days ago

here is the problem here, distilled water contains no magseium or calicum! cannabis loves magniseum and some strains are hogs and require more than some, with canna nutrients, even though they sat they are made for cannabis, they dont have enough magniseum for them so almost always you have to suppliment with some

by using distilled water you robbed your plants of more micronutrients

do not use distlled water, thats why people who do use it have cal mag RO water does the same, peple have cal mag

use tap water as long as its not soft water, like if you got a water softner, if you have one dont use tap cause sodium is bad for plants, and plants take in sodium before other nutrients

do not use that spa ph adjuster, that is not safe for plants, your better off going to the pet store and getting ph adjuster that says its safe for plants, it works well too

you also have the start of nitrogen issues, which is another reason why your problem looks funny

what soil mixture is your plants in?
and why are you using hydroton on top soil when your growing soil?

Here is a question that Lucas answered that might interest you
does epsom salts need to be added to canna aqua flora during flower, or just veg?

both formulas benefit from adding 1/4 tsp epsom [per gallon of water] (it adds 25ppm of Mg),

the Mg level of Vega is 35ppm, the Flores is at 42ppm.. I aim for 60-70ppm of Mg...

its a mixture of bad desicions not to mension bad luck......
it first started when i had a bad soil ph from about 7.1 ..the same day i wanted to feed canna flores and adjust soil ph....before i could feed /adjust my ph meter went Kaput (broke)....i never feed them that day....coz i searched some help on internet first.....
in that time they needed water bad and i decided to ad neutral water thinking i could get away with it....after 2 feedings (on about 5 a 6 days) they started to produce yellow spots on the bottom fanleaves....
(meanwhile i orderd a ph meter from the states now 6 or 7 days ago...still no payment :badday: )
anyway....i went to aquariumstore and bought me ph strips ...with always turn pink.....even wen i add ph - or +...damn crap ...thinking about the 20 $ again :badday: :badday:
so with that not working and out of possebileties i decided to mix spa water 5.2 and my tapwater that is 8.1..nd give this without feedings to make shure a had a aprox.....
now 2 days ago i gave them distilled water and magnesium on sproutco's
advise
and yesterday i 'had' to feed them so i riskt a low level of nutes witch i know is about 7.2 ph ...i added a litttle lemon to drop ph on feeling..... :badday: :fsu:
i did not what else to do ...and i got no watersoftner or something like that..i am realy new at this ...this is technically still my first run....

i use canna vega, flores also pk 13/14 and enzymes from canna No additives...this run for soil i use canna professional or plagron light mix...no add to soil also....


im gonne go look at them in 30 min then they are awake i'l post something after

You did not mention the pk 13/14 before. Adding this to the canna nutrients will agrevate low magnesium levels in it and help bring on more of a mag deficiency. Too high a potassium level in especially canna flores to begin with.

no i did not.... :bat:
now that i come to think about it... i gave 1/2 doses recommened i see on my chart could this be why my soils ph woz F***t up?
:yoinks: :badday:

im gonne follow my friend jaws advise.....not gonne mess around with her....she's 6 weeks now...just gonne give her water and let her finish.....

I would not get too hung up on ph. Magnesium availability to the plant goes up as the ph rises in a soilless mix.

I really learned alot from this thread. :joint:

yup also got nitrogen issues going now to, i would reccomend getting a different kind of nutrient, i always see problems using canna even if they use reccomended doses, its either to weak or to strong its not just right...... and always poor with magniseum and some other micros cannabis needs
