bingo, look at the cotyledons. when they start to die, start feeding. listen to your plants, you can't force them to eat more than they want to.In soil, I usually give 1/4 strength from around 3 weeks. For hydro, 2 weeks The sign for me is when the cotelydon start to yellow a little. This is a sign the plant has used up its energy store and is looking for something to munch on. JMO W
