help my plants are dying... high quality pics.

Pop that plant out of that potter and look at your rootball..it bet you rootbound and need a bigger potter.

It's looking like either nute burn, or additive burn. Do you add any Superthrive, or any micronutes? Do you foliar spray with anything other than ph'd water? Do you know the runoff ph?

Nutrient burn starts showing along leaf margins and tip, filling-in the neckrosis, (brown, dead) from the outside edges, in twords the middle of the leaf.
Leaves will crisp-up and problems will accelerate.

Over-micronute indicators, in my garden, include leaf crisping without the leaf margin indicating problems. A brownish-silver 'greying' of the leaves just prior to and just after 'crisping-up'. (almost a heat-stress look to it)
Using different brands of nutes, they all have different formulations. (also I would look into nutes and micro's already in the Happy Frog) My guess is that, individually, one brand of nutes you are using may contain all you need. Adding another formula, you are likely doubling-up on some of (or all of) the micronutes. I'd re-think your nutrient strategy. (stick with one brand per grow) :thumbsup:

They aren't showing signs of rootbound, but you might want to start thinking about a transplant.
They aren't showing the lockout signs (severe yellowing, with brown blotches, droopy) associated with root rot.

Recommending he add stuff, just to see if it would work, can kill an already stressed plant. Tiz one of the main reasons we have a troubleshooting form. Likely best to wait till all questions have been answered before offering a diagnosis and treatment. (or prior to following a blind diagnosis) :thumbsup:

If you decide to flush well, (I would) let the soil dry before doing so. You might want to transplant at the same time. Would help a little with your toxic soil condition.

I love my Fox Farms line. Have changed a few times over the years, to test the latest 'miracle' products everyone is raving about...but I always return to what works well. :jointsmile:

that's not 'nute burn', folks ... Clue: no burnt leaf tips, that I can see ... I suspect calcium deficiency, you should be using about 10ml per gallon, your teaspoon is a bit light ... also, may be overwatering a bit, let the plant go thru wet/dry cycles ...

I agree with the Fox Farms fertilizer regimen, too ... my best plants have been with Fox Farm, soil and hydro ... (apologies if I missed something in the pics, am almost blind in right eye now ) ... good luck :thumbsup:

finally, some trusted names on my radar, thank you rusty...

and everyone else.. i dont think i have root rot, atleast not yet, but i have been watering maybe a bit too consistent and im going to let them almost droop before i continue..

i now have the entire faxfarm line, grow, bloom, tiger, happy frog, dontbugme, i dont know what im missing anymore.

I do agree a few might be root bound. i was planning on transplanting atleast that one large one, but it is soo large i am tempted to flower it but i want to clear up all issue while in veg.. i might just have to clone it to keep it going.

im hoping all will clear up once i am using only foxfarm...

Also, do i follow their recommended dosage? Isnt their line practically formulated to grow mainly cannabis? At least isnt that the largest purchaser of their products?

Do i go with perfectly clean r/o water, or do i add 2 tsp of calmag/gallon when giving them 'just water'

[Rusty Trichome]

I go with their schedule, with two exceptions.

I go half-strength on the Big Bloom. Indica dom's handle it fine, sat dom's tend to show a little burn. The FF people told me that the Big Bloom and the Tiger Bloom have your micro's, so no need to add more...and that the Big Bloom is the catalyst. (it's a tea of bat guano and worm castings)
Keeping these ingredients in mind, I use an organic peat-based soil with castings and fungi already in it, and have never used Happy Frog. You'll want to adjust the Big Bloom accordingly.

Also, I feed twice a week, instead of once. I cut the rates in half to be less of a 'mega' shock, but they still get the same weekly ammounts overall. Plain, ph'd water inbetween if/when necessary.

The only other additive I use is Soil Syrup. (humic acid) With Fox Farms, you'll get some salt build-up, so monthly flushes are a sucessful part of my regimin. After the last bit of flush, I'll mix-up the humic acid, and add it to the soil then.

If using R/O water, you'll need a source of calcium. (CalMag is fine) Is there something wrong with your tapwater?

Image...what's up with your eye...?

[TheXFactor]

i think i finally figured things out...

thanks to you guys!!(maybe girls,lol)

but there were 3 things that i think we can narrow it down to, each plant had its own issue.. well, that big one, that one of u posted a link of the picture of, that u recommend i transplant into a larger pot, well i did so, and i plucked a few of the dying fan leaves and it has a very gritty mineraly, nutrient flavor, indicating to me high nute content, so nute burn complicated with being rootbound(which if i know anything makes burning a lot easier)

another, in the first set of pics i posted has some root rot, atleast it root werent a pure white and furry, but thing and dull, kinda brown... i replanted it into a bigger pot with dry soil and letting it be for a few days.. then i'll water with just calmag and liquid karma... If any of you disagree with the liquid karma please speak now or forever hold your peace.

so, rootbound, nute burn, root rot. i think thats a great explanation for those dying leaves and spots that keep showing up. Rusty, i think u nailed it.

i'll let you know how things are in a week or 2..

Also what size pot should i use for mothers, and how many clippings can a mum take before its time to toss her a reveg another momma.. they are all in 2 gallon pots.

I've got a similar problem, rusting/curled leafs (specifically the ends)...

My problems undernute and lockout.. it's interesting how overnute looks similar, I'd definately expect your case to be overnuting like rusty suggests... definately some sort of additive/nute/lockout burn...

Good luck to solving it dude :-)


ahh see you have solved things, well done.. ;] be careful the next time you see it , it could be undernute or lockout hehe; I must be careful not to misdiagnose a problem as it can make poor plants die

Here's hoping theres never a first time for us both. Yup it's true never unintentionally killed a cannabis plant!

well im not 100% outta the woods yet.. all i have done so far is a basic repot into fresh soil and put water w/ 6ml calmag, and 5ml of liquid karma. ph was 6.2 when it entered....

Rusty... i spoke to a knowlegable guy at foxfarms, and he said, in soil your always going to have a very low ph in the runoff. the only way to get a precise ph it take about a half cup of the soil and place it into about 2 cups of distilled water, swirl it around for a min then stick ur pen in.

whats your thoughts on that...

Ive taken my plain r/o water and ran it through some fresh soil and the ph was coming out at 3.9-4.2, thats LEMON JUICE!!

so idk, you hear so much contradictary shit among the community its just best to sift through it and listen to experienced...

Still, just a tad too low. As soil degrades, ph will go down further, taking it out of the 'acceptable' range.

Rusty... i spoke to a knowlegable guy at foxfarms, and he said, in soil your always going to have a very low ph in the runoff.

Not necessarily so. I use an organic mix, and I use well water, which comes out of the tap at 8.0 ph. I use ph Down (phosphoric acid) to lower my water ph to 6.8 before watering. My runoff ph is a fairly consistent 6.8. If I run the unadjusted 8.0 ph water through, my runoff comes out at around 7.4. (was done just for testing purposes)
Also depends on if you are taking the readings on a plain watering day, or a feeding day. (nutes have a lower ph)
With any peat-based potting medium, ph will slowly degrade. This is why lime is added. To buffer the mix to around 7.0-ish. This effect wears-off after a couple of months.

the only way to get a precise ph it take about a half cup of the soil and place it into about 2 cups of distilled water, swirl it around for a min then stick ur pen in.

I'm ok with approximate readings, as long as they are within the parameters of a 'normal' range.

Ive taken my plain r/o water and ran it through some fresh soil and the ph was coming out at 3.9-4.2, thats LEMON JUICE!!

Are you using one of those color-coded test kits to check runoff? That would explain the low readings you're getting. The color coded kits needs a clear liquid to show accurate results. (the runoff is tinted, so will tint the color-coded result)

my soil ph is about 7.0 atm :P the buffer goes after so many weeks man. tell the foxfarm guy to consider that... Also, if you are in a hard water area it's very easy to get a high PH runoff. I'm fixing my shit with phosphoric acid, not perfect but does put the PH in the right place for the uptake of nutrients.. :]

my 5 cents anyway :-)
