Please help!! 10 days seedling turning light green

SOLID.....HE DOES NOT NEED IMO TO DO SOILESS.

No need to shout. Lol.

Was only passing along info on coco if he chooses that way.

He could go from coco starters into soil as soon as roots are viable to transplant.

Coco has quite a big learning curve as its more like hydro with EC testing and pH correction.

It was not @ You him,sems he is having a REAL hard time.

No worries.

Some do have a hard time in this game.

I think sometimes people make it too complicated than it actually is.

As a coco grower myself if you wait 2 weeks before introducing nutes you'll have a starved stunted plant.

Hydro nutes don't contain enough Ca and Mg for use in coco without additional supplementation.

They also generally have too much K in them for coco as coco generates K over time and holds on to Ca and Mg.

Look for nutes either coco specific or with around 5% Ca, 2% Mg and under 5% K.

The a and b solution has the following nutes :

210 pm K
1.00 ppm
Fe190 ppm
N0.50 ppm
Mn150 ppm
Ca0.50 ppm
B70 ppm
S0.15 ppm
Zn45 ppm
Mg0.10 ppm
Cu35 ppm
P0.05 ppm

I think that equates to 5% Ca and 1% Mg.

You may need a little extra Mg during flowering if you use them.

BUT I'm not 100% sure the ppm equates to a percentage like I've stated.

Thanks for the reply. When should i start feeding???

Depends if you plan to keep with coco.

 

[lucifer2014]

I dont know. Which is the easiest way? I had a bad experience.with soil mix

 

[jondamon]

I dont know. Which is the easiest way? I had a bad experience.with soil mix

Do you have an EC or ppm meter ?

Do you have a pH meter?

Do you understand about growing with a hydroponic style method and the approach you use to determine feeding strengths etc?

Do you understand how pH influences nutrient uptake using hydro?

Can you ascertain nutrient deficiencies by looking at a leaf with symptoms?

If you answered no to most of these questions then back away from the coco and switch to a low nutrient charged soil.

Also.
For me the easiest is coco but its what I started using in the beginning of my growing journey. Near on 5 years ago.

What nute brand?

K at 210ppm is outlandishly high for coco in comparison to N for example at 0.50ppm.

I dont have a ppm meter, but i could buy one.

Yes i have a ph meter

i understand about growing with hydroponics but i dont have experience.

Yes i can ascertain nutrient deficiencies.

I had a bad experience with soil because the soil mix was too hot. I just wanna grow without too much trouble. My worry is that my seedling is on coco + perlite and i have tu decide what type of soil or method should i use. Another problem is that in my country there is not good quality soil mix, only Sunshine premix #3, #6, #8. On the other hand i have hidro substrates and hydro solutions available on a hydroponic institute. So i dont know which way i should choose.

 

[jondamon]

Can you gain access to things like peat moss, vermiculite, perlite and obviously you can get coco?

I ask this because you could cut the soil mix with any or all of the above to lighten its pre-charge.

Can you get seed starting mixes?



J

 

[lucifer2014]

The sunshine premix #3 is a germination soil mix.

 

[jondamon]

The sunshine premix #3 is a germination soil mix.

And did you find this mix still too hot for seedlings?

Amend it with no nutrient value extras if so.

I havent used that soil mix yet. I dont have other choice here. I could find vermiculite, peatmoss, but i dont trust in the first mix soil i bought. So, i think i wil go for sunshine #3.

There is your answer.

You can even cut the the number 3 with the number 6 when transplanting out of the seed starter for a little extra nutes.

Thank you J. So when should i change from coco to soil? My seedling has 3 days old.
