Do the symptoms include stems turning purple or dark colored from bottom up ?
If so i believe that is a phosphorus deficency. Dont take my word do your own research but if it is the case then some flowering nutes should help it recover. I wouldnt reccomend full strength tho. Hops this helps. Good luck.

As we say 'you are doing too much'

Pk for what?
How old is the plant?
What are you feeding it?
How often?

i have tried epsom salt, can it be because i was watering her at ph 5.1 all this time?

Are you trolling right now?

5.1 pH? Lockout land

5.8-6.3 is your zone

C-a-l-c-i-u-m is not Epsom. They work together.

Coco binds Epsom/magnesium.

i thought it was phosphorus deficiency in morningoo
]and i feed her pk boost with ph 5.9,
did think this one will grow too so i didnt keep the date i planted it but i can guess its 1 month,
i feed her Canna rhizotonic, when seedling and then after 2 knoths Canna coco A and B and rhizotonic.
i use a 2 liter bottle after i added Canna Coco A and B seems like there is white funguy growing in my water, did some reseach couldent find if that was normall, so i didnt change it and i kept on watering her every 4 to 5 days with the same fungi water because she was doing very well and now she is not.
i got to get myself a cal-mag?
thankyou

I have used the entire canna line before. Never seen funky water unless you let it sit without circulation for days and that's how pathogens are incubated.

Lay off the 13/14 until day 14 of flower.

EC no more than 1.6

pH 5.8-6.3

Add cal mag 5ml per gallon(botanicare)
Get spray bottle and mix some camg in it spray once a week.

Do not let water stand more than 24 hours without a stir.


Water less often until medium dries out. Then water a little bit daily/bi-daily not soaking.

Why are you using PK boost on that tiny plant?
I've posted this on several threads recently:
The overfeeding of any plant food can cause nutrient deficiencies.

Isn't calcium locked out below 6.0ph in soil tho? Just remember some charts I read showed ca locked out below 6.0 in soil

so whats the deficiency in my plant? calcium? cause i was watering it at PH 5.1 or magnesium. i have given pk boost to the small plant because i thought it is phosphorus deficiency. i don't think i can grow it, anyways it is still growing i have left it for itself, no more loving her and watching her every 5 mins.

Same as above. You locked out most minerals @5.1 pH. That sheet up there is Ca.

Again Coco binds magnesium into the Coco fibers and releases little of it. Only fix for that in Coco is... more magnesium. Calcium and magnesium work hand in hand in Coco.

Get the pH up to range and add magnesium. Easier just use the Ca Mg and pH right..

Feel free to search:
pH nute lock out, calcium deficiency in cannabis, Coco CEC explained, pH charts, Coco magnesium deficiencies, most common cannabis deficiencies etc.

Good luck.

Water with 5.8/6.0 only for a couple cycles. Coco is Hydro. You need 5.8/ 6.2 for the plant to feed. 5.1 won't work. She can't get to the Magnesium or P. Don't add anything more until you get the pH back.pH_chart7.jpg
