Welcome to AFN. Is there a question here? Some observations based on your pictures. It is too humid and too hot in your cups as indicated by the excessive condensation. Your seedlings will be subject to damping off if they are in that environment for any length of time when they sprout. It looks like you may be watering your pots wrong. Tap roots can grow 9 inches in three days and the lateral roots are only a couple of days behind. If the roots hit dry soil they will not grow there and this will stunt your roots at the most important time in their growth. What you need to learn about watering will come with practice. Here are the basic rules: Never let the soil dry out. Soil and or coco can become hydrophobic if allowed to dry. This means it repels water. This in turn will create dry pockets in the soil and roots there will die. If your soil - coco have accidentally dried out use a surfactant to help re-wet it. I like yucca powder. Don't let soil remain soggy by watering too much too often. Root rot, damping off, molds, fungus gnats and other problems start in soggy soil. When you do water water the entire pot. How to learn when to water starts before you plant the seed. Fill your container with fresh soil/coco and weigh it (heft it) this is the lightest weight and consider it a dry pot. Now slowly water until the soil/coco will no longer absorb the water and run-off begins; weigh the pot (heft it) this is the maximum water, the wettest the pot can get. The difference between wettest and driest is the maximum water weight, for ease of explanation lets just say the water weighs 20 pounds. When the pot loses 10 pounds (half of the water weight) it is time to water again. There is an art to watering.
