Problem with my WHITE WIDOW - PLEASE HELP !!!

Hello everyone,


I/m a newbie and I really hope I can get an answer here as I am having a bit of a problem with my 1 month old white widow. The girl grows pretty fast, but I see the older leaves getting burned and some of the new ones getting their tips burned and curling upwards.

Is this a nutrient burn ?

Here are a more details about the plant :

1. I am using organic Canna Terra Professional plus (on their website they say that this particular soil has been pre-fertilized)
I am growing my White Widow outdoors in a 6 gallon recipient, so no artificial lights

2. I haven't used any nutrients until now

3. These are my PH and PPM readings

PH of run-off water is about : 5.5 - 5.8

PPM of run-off water is about : 3800- 3900 ppm Nacl , measured with HM CM-100 , the conversion to EC is about 7.9 EC

4. My tap water PPM is 150 and my PH is 7-7.2

Okay...I know the PPM/ec is huge for a month old WHITE WIDOW, from what I have been reading lately, nobody does more than 1800-2000 and that's in late flowering...


What should do to lower the PPM ? Do a nice flush ? I never done one before and I am afraid of drowning my WW....


P.S - The plant grows very fast in terms of new stems and leaves but I am loosing the old leaves in the process and some of the new ones got their tip yellowed/browned

Waiting to hear from some of the most experienced guys here

also wanted to add that the PH of the water I use for watering is about 7.2 , and after testing the PH of run-off water the PH is about 5.5 , so almost 2 points down once the water goes through the tank...Is this normal to loose almost 2 points of PH at the run-off ?

If the water going through is collect soooo much nutrient . . .. it's gonna drop the PH a lot . . . .

So a picture??

From your PH to your run off EC . . . you've got big over fert problems, that will be building up salts in the soil locking out other elements, another reason your run off PH is soooo different to what goes in.

I'd get 20 gallons of 6.5PH water and flush it through . . . . .drown it??? Your burning it to death right now . . . . .buckle up, put a hard helmet on, life can get tough in this line of work!! lol



NOTE . . . .6.5PH not 7.2PH . . .the ph of what is going in is too high . . . .

I am gonna do a flush and test the PH and Run-off water after each gallon of water I pour through this plant....Did anyone here used Canna Terra Professional Plus Soil ? You guys say that I am burning my plant and by the looks of it ( EC/PPM , PH readings) and the burned leaves I am indeed burning it, but how did this happen ? I never added any nutrients to my plant, how the hell this happened ?

Is Canna Terra Professional Plus soil so rich in nutrients ? Does anyone has any experience with it ?


I should also note that I never re-potted...My WW it's in the same pot since she was a seed, a 6 gallon pot

You've not fed them anything???? With 7.9EC run off ?????

I think Canna Terra's are pre ammended at about the 1.5EC level . . . . .wow this is wierd . . . .

How old is your EC meter, has it been cleaned and calibrated recently?

Yes, I never fed her. Never. I have a HM Com-100 which comes factory calibrated, the toy is brand new and I have no reason not to trust it's readings...

Now about what I did yesterday :

I flushed the plant until the run-off EC reached 1.5 or 750 PPM Nacl and a 6.0 PH.
I didn't pour just 2 times the pot's size of water, I've read the EC/PPM after each flush until I gradually reached 1.5 EC (750 PPM). To be honest this happened only after 3.5 gallons of water, my pot size being a 6 gallon one.


Now what should I do next ?
I was thinking at this :

1. Wait 2 days until the plan recovers from the flush (it appears all the leaves are back up after 8 hours and are not dropping anymore)

2. Test the run-off water tomorrow and see where I am heading


Basically I have two options here :

A) If the EC/PPM NaCL is going down I should start to feed her, right ?

B) If the EC/PPM NaCl is going up I shouldn't do anything but monitor the plant and make sure it never reaches a 8 EC/ 4000 PPM Nacl

But the question is, what run-off water EC and PH should I be staying in to be safe ?? My White Widow plant is 5 weeks old, what EC should the run-off water be for a plant like this in ideal conditions ? Of course I can watch the leaves and make changes accordingly but I do what to know what the PRO's are doing.

Like this guy who has a medical marijuana shop and youtube channel and keeps his run-off water at 3.1 EC or 1600 PPM , he says this run-off is ideal for a plant this size, do you agree ?


My 5 week White Widow is pretty similar in size with this guy's plant, about 24 inches/60 cm tall (measured today)

With a few pictures we could tell you so much about your plant, I'm not being an ass but most of us diagnose problems visually. Peace, Be Safe MD.

High again . . . .

My run off, even after feeds never wanders over 2.0EC, it's a light tan color after feeding. BUT I only water my plants once a week, I constantly feed a much weaker solution all the time, yes, in soil!!! Coz my microbe count is off the chart, so they work hard for me, processing nutrient.

If you're, traditionally, big feeding (gorging her) then starving her, I guess run offs in the region of 3 to 4 are ok just after a feed . . . . .

So your option now, is to carry on with one more watering allowing for 10% to 20% run off every time you water or feed.

Then what I would do, is start the feeding again at 1/4 strength for the next few waterings, see how she turns around :)


(Just out of interest, have you been watering until run off recently, or have you been watering enough to keep it damp but not enough to have liquid pass through into your container below the pot.?)

the thing is that most smartphones attach a geolocation info to all pics made via phone, so I need to edit the photo's properties to stay safe....will do that and post some pics soon

I started my seed in a 6 gallon pot, so at first (1-3 weeks) I didn't water it until there was run-off pouring out because I considered the roots to be small and not actually reaching the run-off. After 3 weeks, as the plant grew larger (over 15 inches) I started keeping a heavy medium with run-off water every time I was watering and at about week 4 the first signs of trouble appeared .

The older leaves got scorched and I lost about 3-4 leaves after week 4, but the plant was growing incredibly fast in the upper section with new branches growing hell fast . I continued for another 3 days and than i saw the tips of the upper newer leaves curled upwards and with burn signs. That's when I stopped and asked for help buying a good PH meter and EC/TDS meter in the process.


Before flushing between week 4 and week 5 I did a watering every 2 days with lots of run-off water coming out every time . As soon as the run-off water went missing, I watered again , I was basically keeping a very heavy medium because the plan seemed to grow incredibly fast this way.

My first impression after reading quite a bit in the last few days is that the White Widow strain is very resilient and forgiving to newbies. I did a lot of mistakes and my plant is still pretty big in size for a 5 weeker (over 24 inches/60 cm) and lost only 2 sets of leaves.
The seeds I purchased from a known weed shop in Holland, so I know for a fact that they are authentic. Like I said, my first impression is that the White Widow strain is very forgiving no matter how hard you abuse it.

So it's possible your little waterings were enough to flush nutrient already in the soil down to the bottom of the pot where it collected to toxic levels. You've probably left a few HOTSPOTS here and there too.

In the future, if you are going to plant a seed in it's finishing pot, you'll need to flush the container of soil FIRST with PHd water, then plant the seed in a totally soaked medium, ensuring there are no hotspots . . . .this is what has happened, hot spots in your medium that is ruining parts of your plant and as the roots grew into the toxic zone at the bottom, the burns started appearing. (This applies to your Canna Pro as it's quite strong for a seed, the alternative is to buy a light soil mix to start your seed.)
