Are you already fertilizing? It looks like Plagron soil, which is pre-fertilized for 2 weeks. For the next few days, just use plain water. Your ladies are still too small for flushing. And when you start fertilizing, use only a small part for small plants; for example, I started with 0.25% of the manufacturer's dosage and I'm still not at 100%... so you don't necessarily have to fertilize that much. Check out my diary... they all look really good and are growing like weeds, and I have hardly fertilized at all.
