when to start nutrients

When should I start giving my seedlings nutrients 3days old now don't want to start to early and kill them

It depends on the medium you grow in. If soil, if it has nutrients built into it (which, usually is a bad idea starting out unless you have a soil that is expected to carry the plant all the way to the end with little help.). Usually people say after the first week. But, if you bought a potting mix like MiracleGro with a lot of nutrients in it, it will be a guessing game when to feed.

Which nutrients did you buy?

I have more grow "grow" its going to be in a hydro dwc set up

I would start in 3 week.

Yes to 3 weeks. 1/4 strength. Alternate plain watering. Stay at that dose....observe a couple more weeks before upping to one half strength. Strain will let you know what it likes. Some are heavy feeders, others are finnicky. I never go past 3/4 with other additives.

If it's soil, start adding nutrients after about a month. Soil should already have a lot of food in it when you start.

If it's hydro, you should start with 1.0-1.4 EC nutrient solution from day 1 if you don't want malnourished seedlings/clones.

Head on over to the hydro section for this. I have miserably failed several times at hydro Soil rewards me everytime.
