Multiple Deficiencies? Please HELP +Rep!

Alright you guys, I'm facing a problem much bigger than myself, hope you can help me:

Direct Link to the post in my Journal (all the info you might need to help with a diagnosis)

All help is appreciated and rep'ed!

what are you feeding youre plants in terms of ppm/ec. and what are the ratios and what in the feed or what brand is it. i go have a closer look at youre journal and get straight back to you

What base nutrients are you using? It looks like you are deficient in more than one thing. Also, what's in your soil? How many gallons per pot and how tall are plants? Is it possible that they are root bound or have dry pockets? When you water, have you picked up the pot a little bit to see how heavy it is?

Hey there, the brand is Advanced Hydroponics, the line is Dutch Formula: Grow Bloom Micro with the following NPK Ratios:

Grow: 25/12/50
Bloom: 00/50/35
Micro: 45/00/10

I used manufacturer's recommended dosage:

Feeding chart - Advanced Hydroponics of Holland Dutch Formula

And I also have Atami Bloombastic: which comes at 00-20-21 (EU labeling, so it's 00/14/15 in US standards).

Plants are in Soil, light mix for young plants so it only had nutes in it for the first couple of weeks which are now looong gone.

I water once the soil becomes 80% - 90% dry and keep pouring until 20 - 30% of it runs off from the bottom.

I vegged for 40 days and gave the first feed at around day 25. At this stage I alternated: water / feed / water.
I went into flowering, day 44 so far and I have only given her two flowering feeds so far, alternated with molasses and cal/mag.

I make sure the PH is at 6.2 - 6.6 every time I water. No EC ppm meter here...

Much appreciated for any help!

It's a mini scrog grow, in a 1x1x2 feet area (2 being the height) so it's a pretty small and compact bush, heavily trained it is barely over 20 inches in height with the pot.
The pot I'm using is a hacked airpot, shallow but wide. 3.5 gallons all in all, but only has like 2.5 galls of soil in it.
Yes I pick up the pot every time I finish watering, it feels twice as heavy.

Gonna post a few posts from my journal here for your convenience

April 20 - Day 85 (Flowering 44)
It's 420 time!!!!




EVERYONE GRAB A SPLIFF!!!!! WE'RE RUNNING OUT OF TIME!!!


It's been a while since I posted an update, and looking at the calendar today seems like the best time to do one ^^


First the good news:
She has been packing some more weight, the buds are heavier, denser, compact and are starting to get frostier
Lately I have been giving her Molasses, I also started on the flowering nutes.

Now the BAAAAAD news
Seems I'm constantly being plagued by deficiencies :/
From what you can make out in the pics above, I suffered from N deff, and seems that the problem is still persisting.


I'm sure that N is not the only concern here, take a look:

As you can see from below the canopy, all lower leaves are long gone, middle leaves are almost gone, things have been slowly decaying and falling off on it's own, no matter what I feed her....I even give molasses to make sure she takes up as much as she can from the soil, and to prevent salts buildup I always water until 20% of the water volume comes out the bottom.


I got red stems (not the main stalk or branches, rather the stems connecting the leaves to the branches), yellow tips and slightly pale green leaves (while younger leaves are maintaining a dark green color), I even have a couple of leaves with Necrosis.


Take a look at the dead leaves I removed just now (there were non 9 days ago....) They look as if burned, necrotic, dry and crumbly....the blades have curled up if that means anything....


I got two branches from below canopy level that are completely yellowing, necrotic and I'm pretty sure they wont make it.


Here's what I'm thinking, this can be a P/K deff now, with a Magnesium deficiency.
What do you think? I would be very grateful to hear your diagnosis


I need to fix this urgently! I'm at day 44 of Flowering and she seems like she still has at least another 20 days to go (At the minimum as I feel that even at day 60 of Flowering it would be too early to chop chop:/), But I am starting to have doubts that she will make it to the end.....Might have to chop early :/




HELP!!!!!!

Thank you for taking the time to read and comment

Does your plant have a total dark period. The twisted stem could be from a light leak unless you pinched. I would say yes for sure there is a N def and from the look of it possibly a small cal/mag def. If you have any kind of one a day vitimans in the med cab, go grab one cut off about a 1/4 of it, crush it up and mix it with some water and give it a go. Make sure all the powder is disolved before you add it to the girl. Just my two cents!! Hope it helps

Yes mate, total darkness! I built light traps and mounted them on the intake and exhaust, also all other cracks and fissures are caulked.
I pinched and trained them heavily around the screen, like under, over and through the openings, so with time my stems twisted around themselves.

I used cal mag tablets (meant for human consumption) crushed into a powder and mixed with my feed a few times during this grow.

Well, it seems to have gotten worse today....gotta apply a remedy today!

Repped everyone here, I'm still open to opinions

I'm actually guessing rootbound, other than that at this stage it's unlikely you can remedy this, a slight increase in some sort of nitrogen may help delay the dying off a week or so maybe, but i wouldn't over do that, If the plant doesn't think she can feed enough off the leaves, she will simply finish earlier, so you'll still get your smoke on, don't worry, she'll go for a while longer yet. the buds look beautiful and healthy, and she won't die on you , just think of it this way, you're going to have some smooth smoke, that you know isn't over done with nutes

good work mate. no need to worry

Thanks bro, that's a huge relief

So far the feedback I got from the community is as follows:

Most people agree I have an N deficiency, but this is naturally occurring since the plant is moving it's N upwards (purple petioles, yellow leaves), a Signal that she is trying to finish early (and the reason I suspect is just like you said, small pot, root bound).

I got a couple of people hinting that this might be also a cal/mag issue, but at this point I don't think that this is the case as I have fed her cal/mag 3 times so far since end of veg and flowering and I always use a 1/4 mineral water (rich in Cal and mag) worked into my watering every time.

Potential salts buildup? I really don't know.....flushed her twice so far during this grow and I always water till the pot is saturated and a third of the watering comes out the other end....not really sure on this....

Well so far I have a couple of recommendations:
Work in some miracle grow vegetable soil on the top or use other means to amend N slightly.
Or Flush her with a full strength nutrient feed appropriate for her stage in growth.
Or Start giving her plain water only and think of end flushing soon.

Gonna have a couple of beers, mull things over and see what I'm gona do.

Well folks, I thought about it and here is what I did:


I added another 2 cms of quality potting soil on top of the existing soil, and watered here with plain water with just 1/4 of the recommended dose of Micro (45/00/10) only. At PH 6.8.


Now the waiting game starts, let's see how she reacts to this after a few days.....I'm hoping for the best.


After this, I'm going to give her plain water only the next time (once the soil is completely dry), one shot of full strength flowering nutes thereafter.....and it's going to be all up to her what happens next, either she recovers or stabilizes, or I start the final flush and aim to harvest at the most appropriate moment.


Wow, I'm anxious to see what she thinks about it


thanks all and stay tuned

Hey buddy, sorry I forgot to check back. Yea I'm still gonna go with root bound. Definitely N def. and probably salt build up. I think that you should check it and make sure it isn't root bound, if it is, replant it as gently as you can into a bigger pot. Check the roots, make sure they look healthy. I would FLUSH on your next watering in case there's salt build up and then go back to your normal feeding schedule and give it a little N. I grow organically, so other than that I don't know if I have any info that can help you as I don't have much experience with chemical nutrients. Good luck!

Hope all goes well and it turns out the best.
