x4 autos, difficult start.

[Jonobo]

Hi AFN!

Here I have 4 autos that I recently started in my new closet set up. I am turning myself to AFN as I never got any reply from the other forums.

I have likely done many things wrong with this grow, not expecting a miraculous fix anymore, instead understanding my mistakes and learn from them for the next grow. Any help is welcome

side note, this is my first time:
- growing in coco
- making my own compost ( was I suppose to let it "cook" in the medium before planting? )
- germinating seeds in a big pot

No need to say I definitely got a few things wrong!

The ladies are now 18days, clearly stunned, germinated in the medium ( 2-4 days to pop out )

With no further due here we have:
- x2 Amesia Haze Auto
- x1 Northen light Auto
- x1 Blueberry Auto



Set up:
- 60'x24' closet
- KingPlus 1200w ( 90cm from plants )
- humidifier
- oscilate heater + x1 thermostat control
- x1 oscilate fan + x1 fixed fan for fresh air intake.
- 10L fabric pot

Day temp: 25c
Night Temp : 20c
RH : 60% on average
Lights: 18/6

Medium: ( from royalqueenseeds.com )
· 3 parts coco
· 3 parts home made compost ( as mentioned above, was I suppose to let it "cook" in the medium before planting? )
· 2 parts perlite, pre-wet
· 1 part vermiculite, pre-wet

I thought that compost alone would do the trick according to some guides then learnt that definitely not so I was planning on top amending with Kelp, neem, crab, alfalfa and dry Fertiliser.


The plants have always looked fairly healthy, never showing any external sign of stress despite the stopped growth. The 4 stopped at the exact same time. I'd like to figure this one out to avoid making the same mistake for the next grow.

Thank you all for the read!

Hiya @Jonobo

I'm a noob, so I can't really help much, where did u get your seeds from I'm doing an auto blueberry as well it's from dopeseeds it seems to be ok now was stunted to start with.

With the medium I think your meant to let it cook first or itll be too nutrient rich. I just used regular compost mixed in a small amount of fishbone and blood meal, and a little bit of veg nuts a meal to a litre of water is what I used, and the day before I ran ph water over the soil until draining twice. I know have the issue of whether to report 2 into bigger pots but I think it may be too late. I'm stoned so I'm just rambling now lol here's a pic of my blueberry, shes had a bit of a growth spurt

Hey man, I'm an outdoor soil sorta guy but from what I understand coco is a lot closer to hydro than soil and needs to be treated a lot differently than a soil grow. With coco it's my understanding that you should be feeding with every watering aswell as being pretty precise about ph going in. Someone who knows what they're talking about better than me will be along shortly to help out I'm sure. In the meantime here's a link you might find useful to have a good read of about your chosen grow medium.

Also, what kind of water are you using and what ph range are you using? How much have you been watering? Do you have run off?
Coco uses hydro parameters.

@Cannakisses seeds are from ILGM. Your BBY looks all right how old is she?
@AutoWonders tap water pH5.8. being seedling I have been told to not add anything to it until early veg especially with compost as she can feed on it for a little while.

Watering wise, I barely soaked the whole medium before planting so there is a chance the roots grew into fairly dry coco which is pretty bad for what I have read. Fixed the issue. Watered it once 500ml and twice 1L since.

Also, this might be a couple of very stupid question but oh well :
- being stunned for so long and still look healthy how does that work?
- if the plant is stunned for let's say 2 weeks ... her clock is still ticking right?

 

[Jonobo]

For a 3rd week .... was about time to see some movement ... for being stunned for more than a week so early in the seedling stage some of them are looking fairly healthy aren't they?



Feeling pretty confident now the problem was created by the very hot medium due to the inappropriate compost / medium preparation.

However I cannot see any signs of burn ....

What do you all think ?

No feeds at all, just the compost? Did you take any pH reading of this custom medium? Coco is not a forgiving or easy medium to deal with, even if you try to make some sort of "soil" out of it, it's still considered a soilless medium.. it has a lot of unusual properties, cation exchange capacity (CEC) related, and con't be treated like a true soil unless the amending is very complete,... most blends still have some peat in it too,... So, with no food going in, uncertain nutrient content of that compost (and incomplete balance of them), no pH known, no run-off generated to test for ppm and pH, and unknown water pH/ppm, this is why they have totally stalled and stunted,...
...best you can do is feed them a proper nutrient regime, learn more about how to grow in coco, but that said, at this age and stunting, I'd consider starting over, sucky as it is,... the clock is running out on then at this age, no miraculous growth is going to happen,...
....get away from coco totally until you've learned all the do's and don't's of coco, how to best run it (cannot be treated like a true soil)... I recommend going to straight soil, like Roots Organic original plus some extra EWC in it,.... no matter what, you need to be able to test in-pot pH, with a quality probe,--> hsoil:

Are you counting the time from when you put the seed in the mix or from the first true leaves?

I agree with @Waira but I have a long shot idea. First I am hoping you are counting from seed drop and we have more time on the clock. Second. only in extreme cases do I ever recommend flushing, I think we are there. You need: EC meter, PH meter, PH Up/Down, Cal-Mag, Humic Acid, Kelp Extract, Hydroponic friendly fertilizer 10-6-15 Plus minerals. (preferably one designed for cannabis). When I say flush I mean flush. PH a 5 gallon bucket of water to 6.1 aerate it overnight if you can and flood the pot slowly until the run-off is clear. The idea here is to start with a clean slate. Hydro is very difficult but it can also be very forgiving. Now treat the grow like hydro fertigate immediatly with 60% strength nutrients but up the Cal-Mag by100 PPMs the first day and then 50ppms every day. Use the humic acid and kelp in a 5 to 2 ratio. That is the bare minimum of what you need to perhaps save this and you need it ASAP if you cannot acquire ALL of these components IMHO these plants are doomed. Other additions that would be helpful is Mykos, B1, L-Aminos, Yucca Powder (surfactant), a bio-stimulant foliar spray of Fulvic Acid and Kelp 5:2, B1, Amino Acids Glutamic acid and Glycine acid. Look for L – Amino Acids. Even if you do all of this it may not help. It is all I have in my arsenal.



and tag me with what you decide to do.

 

[Jonobo]

First helpful and realistic answer in weeks.
Thank you @Waira and @Mañ'O'Green for your replies.

Yes I am counting from when the seed has been dropped in the medium. However I do not have most of these ingredients.
I have already grown successfully in coco with synthetic nuts which I want to stay away from.

I have learnt a great great deal about organic growing by finding answers to all these mistakes , I will put an end to this grow to avoid wasting more on the bills.

I am waiting on all of the dry amendments and quality EWC to be delivered for my next grow with super soil, same strains. ( only have to figure out the "not burning the seedlings with the super soil part ).

Thank again for your very detailed helpful replies
