Northern Hemisphere Duckies

Moved them from the peat pots - I was afraid that they would not break down in soil as advertised. Luckily, they are very easily removed without disturbing the soil. Planted them a little deeper, just up to the cotyledons. The weather has been dismal but they are doing their best. They've been planted into compost/coco/perlite in a 2/2/1 ratio. Substrate drains well but for now, I've been watering very sparingly around the plants to try to encourage root growth. Watering 3-4 days. One of the plants has stunted leaves and strange yellowing. I notice it at this point but asides from leaf size, the plant is growing at the same pace as its brethren. So far all three have their differences.
