Surprisingly slow growth, but the colour on most of them looks healthy. Plant #4 might be a goner, it had problems getting out of the seed and nearly died the other day. It's likely just going to be a very weak plant. Keeping my fingers crossed though.
Update #1: After getting some helpful advice from Mark at Dinafem Seeds, I transplanted the three largest ones into 7 gal smart pots and placed them outside where they will stay. The remaining two will likely head outside either tonight or tomorrow depending on the weather (these are the smallest two, #2 and #4).
Update #2: As of June 2 (Day 13), all plants have been transplanted into 7 gal smart pots and will remain outside.
