please help, I think its going to die :-(

Hi,
can somebody help me to figure out whats wrong?
The pics Show her, her roots and how she looked 3days ago...

Like 6days ago I added much stronger led light.
Temps go up to 28°C, and go down to like 18°C at night time. Yesterday i decreased light power and temps go up to like 25°C.

3 days ago i watered thouroughly with runoff and 2ml/l Biobizz grow.
Soil is biobizz light mix+ allmix.

Its the biggest plant, but if its too much in nutes id think the other plants would have much heavier issues right now...

Its getting worse every day... i fear if it continues for like 3-4 more days its too late for anything

PS: can i somehow determine the order how the pics r Shown? Names r 1-5...but 5 (3day ago Picture) is shown first...middle pic is named 2...so its like in no order at all, is it random?

Are they limp? If not, looks like a severe ph issue

i'd guess a ph issue or over watering.

peace, bozo

sry im not english, what do you mean be "are they limp"? the other plants look ok, a bit droopy, but not remotely anything like this.

Looks over watered/soil staying too wet.

thank you all.
So should i actually try to Keep it @ 28°C during light time? More water uptake and also more Evaporation?? or is that a bad idea too?

And why did i read so often: better water only a few times but then do it thourougly with runoff, so is that actually bad advice? I was watering like once a week...

Tomorrow im getting smartpots delivered, should i transplant ? (but it has more volume, so id Need to add like 10litres more soil)

cut back on your watering for now and 'heft' your pots for how heavy they feel, don't water until they feel noticeably lighter, ...it really does look like 'wet feet' to me which was a problem for me at one time until i switched to coco hempy buckets which cured my problem completely.

...coco hempy buckets are awesome man, passive hydroponics that kick's ass!

...these were grown under a 400CMH in 2liter Coke bottle coco hempy 'buckets' and each yielded almost 2 zipz so almost a quarter elbow in 4 liters of coco.



good luck, bozo

thx, well my first Goal is to make it to the end, as soil is supposedly the most simple way...maybe next time kinda jealous how much faster plants grow in dwc

Looks like it needs less water & some cal-mag.
temp I like 66F to 74F and night, looks to me like it's getting to cold some strains don't like that.

yea its in the Basement, as noone is "living" there its like 18°C when lights r off. I already turned the heater on now, but seems such a waste of energy to heat up whole room just for my "cabinet" and then on the other Hand really have to put an intake in my cabinet, with just 220W of led power it gets 28°C in there (seems sucking in air via random gaps/door because of the exaust isnt enough) , and down to 18°C at "night" also seems really too much...cal/mag i used foilar epsom spray (after spots appeared), as for cal i think the tap water should/could cover that, right?

Oh noes, it doesnt get better, the other plants started to look bad too...

Is there really nothing i can do?
Does it still seem like just overwatering?
I smelled the roots, for me it just smelled like soil...

For weeks everything went like perfect, one freaking watering and all the work is for nothing so many guides tell you to water plenty with runoff...just as i did...why

I just read that whats Happening to me is when you contantly overwater, but does the first pic in my first post look like that?

now its almost dead, wiliting all over the place...great Forum :-/

Click to expand...

...so it's the forums fault you haven't done your homework?

bozo

how did i not do my homework?
Did my the first pic in my first post suggest that im doing it totally wrong, which is only like 5 days ago?
I watered just as in 100 guides suggested -throroughl...first time i did that actually.

I asked for help, because im obviously desperate.
I asked wether i should increase temp or not, I asked wether I should transplant or not, something to improve the situaton.

I get no answer, and i mean "cut down the watering"...I was not really about to water it again, as thats kinda common sense there...

trying to get Information isnt that easy...e.g. id find: "increase light intensity and heat for evap" next Thing is "lower temp and put it in a rather shady place

just how it is, helped a lot of People here with electronics, now im in Need, but guess there is no such Thing as Karma.

Flush your plants with tap water 3 x pot size (if pot is 15 liters, flush with 45 liters of water). But before that, oxidize water with air pump for few hours (to vaporize chlorine out of the water and get Ph level to around 7). Flush with 3-5 litters at the time, wait until all runoff is drained, check Ph and PPM of runoff. Flush until reading get to (Ph 7, PPM 100-200). That's how you neutralize your soil from all fertilizers. Now oxidize some more water (same amount as your pot), add 1/4 of the recommended nutrients, add Liquid silicon (It has good healing effects on plant as well as it adjusting Ph ), than check your Ph, (your goal is 6.4-6.6 for soil), If needed adjust it with liquid silicon, or drop it down with Ph down solution (81% phosphoric acid). Mix your water well and check your Ph after each drop of phosphoric acid, as far as I know 1 drop per liter drops Ph by 1-2 so be careful with it.
You probably know this anyway, but do not use any flush agents during flowering, only last 1-2 weeks before harvest.
Water only once a week or when needed (when pot is a lot lighter then when its just been watered)
keep your light at least 16"-20"
Wipe inside your tent with light bleach solution once a week.
Hope it is not to late.

PS: Never tried it with cannabis personally, but in theory that's should work well, well lets be honest, there is not much to lose at the moment!

OK first are the leaves dry or floppy? It looks like you over watered the plants a bit in the last three photos since 25-28C isn't that hot (I've had my plants up to 35C and they didn't do anything too bad)
The first picture looks like it might just be a little lacking in nutrients since it's extra yellow on new growth but just give it a normal small feeding, nothing extra.

Hopefully that made sense, I'm tired.

The actual PH goal for cannabis is 6.5-6.8 make sure to check that out because it's always a big problem usually with an easy solution if you catch it early.

its crazy, but is it possible that u gave me all the wrong diagnosis?
Or what might have happend there?

As it got worse and worse and i got more and more desperate i tried several things...one involved watering...

And now 5 hrs later, it just looks like its gonna be ok...i mean still a bit droopy, but nothing compared to the pics at the top of this page...

Yeah, it does look much healthier. What did you do to it?
