Bongkhananswered grow question 4 years ago Lift the pot up and notice the change in weight. That is by far the best way for small plants. Also top 1 inch dry ; time to water. Consider watering 500ml in one feeding and wait till they dry out if your plants are 2 weeks old. Slowly you shall notice that it dries out quickly and when you water a little more ; it grows more. Slowly and gradualy increase your feeding. Hope that helps.
