Whats up growers
Welcome to my diary

Grow box:
85x110x230cm box (21m3)
Inline fan at bottom and exhaust fan at top (200m3/hr)

Light:
Mh 400w
18/6
100cm away from seedlings

Medium :
Coco/peat/perlite

Seeds:
1x 3weeks old ak47
2x 1week old critical kush
1x 1week old chocolate haze
1x 1week old ak47
All royal queen seeds

Nutrients :
Apk 20-20-20+te
Cal-mag+N

Currently problem is that 3weeks old ak seems too small but cotyledon leaves are completely yellow now
Is it time to feed her? And what nutrients? Cal-mag or NPK? Foliar or root feed? I haven't watered them foliar at all
And what are those yellow tips?

Seeds don't need food for weeks , nor a strong HPS 400w so keep that at distance if u don't have a CFL.

Your fan is weak. Get a stronger fan and use that one for air in.

Leave seedlings alone for a good couple of weeks. Only add water when they lighten up.

20/20/20 food? Use some proper veg nutes for MJ plants.

Hey dude and tnx for quote
I do have cfl but i don't care about electricity and as u said im gonna keep that MH lamp in 1meter distance
Is that enough?
And what u think about that yellow tips any idea? Could be because of ec of medium?
And when to feed her?
I've heard u should feed them with cal-mag after a couple of weeks when u grow in coco but not sure
Isn't she too small for a 3 weeks old plant?

The light is good where its at, But what Iahadaextranjer is saying that you don't need that strong enough light for seedlings, Sometimes you could fry your little babies under them, But your seedlings look ok

The medium I'm pretty sure has Little to no nutrients in it, but that doesn't mean you need to supplement it with food right away, Coco is good for at least a month without the need to feed I veg'd a seedling for about 3 weeks in a small coir pellet feeding it only non-ph'd tap water, straight from the TAP

You won't need cal-mag or any other nutes right way, Just keep feeding it water in till you see the new growth go from a dark green to a light yellow-ish green, Your plants will tell you when its hungry, Right now what your doing is like trying to feed a toddler, A T-bone!

any don't compare your plants to other plants at 3 weeks, this can make shit very confusing, because people often start counting the weeks from seeding being germinated, or seedling popping from it's shell, or seedling breaking grown, or Seedling growing first set of real leafs!

The best advice I can give right now is DON'T FEED, use just good ol PH'd water at least for the next two weeks, And get a fan on blowing on those stems

The burn tips are a pretty good indication that ur shits 2 hot...as earlier stated u shouldn't be feeding em this early.

Lol what was that about?

 

[AmirR]

Temp is about 26-27 when light on and 25-26 when light off and there's a fan blowing between seedlings and light
How to cool it down if its necessary?

Tnx a lot bro that was accurate
Then i won't feed them
Im using spring water with low ec and tds and we don't have any ph down solution here so i used a few drops of lemon juice to ph my water could it hurt the plants?
And there is a blowing fan blowing righf between seedlings and lamp

 

[smokefacekillah]

hmmm maybe try just water,When I first tried using lemon juice as ph down, the pH would fluctuate like a mother fucker, But I run hydro so pH is really important, but I know some coco's usually have a pH range of like 5.6-6.8 so maybe you don't need to ph the water but I'd get some pH down asap your going to need it when you start to feed also get a nutrient better suited for marijuana

Also what Slippery bandit means by "your shits to hot" is that your medium has a lot of nutrients in it, It's a term that confused the fuck out of me so bad I said Fuck it and went with HYDRO it seems way easier to me , But yeah it means your medium is so nutrient rich It could burn the plants, Hence the term HOT!

Fine so better to stop lemon juice
What if i use pure acid? Im pretty sure there's not any ph solution around
What are those solutions btw? Is it something more than acid?

I wouldn't DIY any kind of shit like that

start reading up on other coco grows as well, I grow hydro in straight Hydroton on flood tables, Which to me feels like the easiest way to grow, all I really do is change the res like every 2-3 weeks I'm using lucas formula , this allows me some leeway with my plants, I can have different strains, at different stages of growth, with little to no negative issues, I just have to move them to a different table when I flush with just water!
