Nutrients for Seedlings

Ive got 5 mini seedlings under a 150w envirobulb.
They're currently in rockwool cubes (the roots came through the small ones so they're in bigger ones now)

There all about this big

The seed membrane leaves are dying down now and the main leaves are looking green and healthy.

I was wondering however - when should i start feeding them nutrients? There just munching water at the moment.

Also im planning on transporting them into pots filled with coco, so would i be right in using a watered down mix of coco a and coco b?

I'd leave 'em another week Dr but make sure you're water is ph'ed correctly, give em another week or so then build up the nutes gradually...

Thanks neo - watching them grow as big as they have done without anything but water is kinda frying my mind. Out of the 5, one of them is very slightly droopy compared with the rest, that's what made me think maybe i should start adding a bit of food in.

Thats exactly it though - they're in rockwool not soil - thats why i thought i should feed em something weak?

lol, like the diagram.

i wouldnt give them any nutes until 3 or 4 weeks from seed. i started mine off on molasses on the 3rd week then went and got some nutes.

with hydro after the seedlings are two weeks old you could feed them a half strength nutrients solution, but like smokeh said its probably safer to wait till week three or four

this is why they invented clonex

you mix it with water, and you ph ballance it to 5.8, and you keep your rockwool moist with the spray bottle.

I would wait 3 weeks the seeds have natural nutes let them use them first.

Clonex is not a fertilizer, it is a rooting hormone.
