When start giving nutrients?

It's been almost a week. Friend put the seeds in a napkin for 5 days. Planted them yesterday in rockwool. The roots are barely touching the water now.

I'm about at the same stage with my TW sprouts and I gave them 300ppm of nutes this morning.

wait until the cotyledons fall off before you add nutes, do one shot with bloom nute as they make your roots explode then go with the veggie nutes till flower, usually 3wks but I'm not a hydro grower so maybe you start sooner.

If that were the case, I'd have some dead plants. I've got 4 week old plants with the cotyledons still green and intact.

Seedlings are born with about 2 weeks of nourishment. Nute at a diluted rate then and work ur way up.

Is this a DWC system? I would have 1/4 strength nutes in there right now
I start my seedlings at 1/4 strength and there are no ill side effects

in hydro you need to feed from the start with a very low dose and build up to the max dosage.
I fertilize my coco\perlite plants from their first watering after being planted with 1\3 strenght.

In DWC you would probably want a lower strength.
