Seedlings keep dying around 3 weeks

[Evlnis]

Hi, I’m new to growing so I could be just making mistakes.
My ph is 6.0
600w approx 2 Hand lengths between plant an bulb
60/40 coco perlite mix
1x1 tent
I have germinated seeds an also just put the seeds into the pots under the light..
I get to about 2-3 weeks then they jus start going yellow an leaves start to die
I’m using cal-mag also at this stage..
These are feminized seeds not autos that I’m using.

Pics always help

600w light, that's pretty close, what light, do u not own a measuring tape?

How often do u water. And Coco needs nutes from the start

So sounds like a few issues killing yer plants

Have u researched growing at all?

 

[Evlnis]

Sorry, I keep the light 35cm away
Cal-mag I use from the start
I water it once a day 250ml
I’ll get a pic in a minute an load it

Sounds like they get hungry and die. Chris is right you feed from tge beginning with coco. Not much but you have to give it something. Coco has no nutrients whatsoever.

What light???????

600w halogen

Lol

Did u just pic a distance?

Why did u pick that distance?

600w halogen

Are you sure its halogen and not Metal Halide? Cause if its halogen and 600 watts at that your burning it. Halogens creating an immense amount of heat. Not good at all for growing. Are you keeping track of temps in your tent?

600w at 35cm is much too close for seedlings no matter what kind of light. That seedling looks baked to me.

It’s a 600w hps...

Just my 2 cents, your light is too close, I would start in soil or jiffy puck and when they are bigger then transplant into coco. That way you can skip nutes until you transplant.

Ah ok. That's not halogen it's High Pressure Sodium. It's too close and too strong for a seedling. Most people will advise a CFL or LED tunned way down.

Coco
HPS
Nutes

It takes work and research to learn to grow

Sounds a plan might have to give it another crack then

Best thing you can do before burning through more seed money.
