A Good Time to Start Feeding?

When is a good time to start feeding your seedlings?
Mine are about 17days from sprouting...

yeah u should be good giving them half the dose of nutes

look like they got some sort of problem - heat , ph issue

Low dose of nutes are OK

What's consider light dose?
Should I use a droplet and only use a couple drops?

use the suggestions on the back of the bottle, usually 1/3rd strength

i usually wait till they are 3 weeks from breaking soil.....and then start at 1/4 strength and slowly work up to half...
