Greetings! Has anyone seen this before? This is a Wedding Cake seedling that was planted 29 days ago. I germinated her in water and darkness for 48 hours and then wet paper towel for 48 hours more. The cup is a sphagnum peat moss and perlite mix. I've had 5 seeds going and they've been on 14-10 light schedule under a GE LED 1600 lumen 6500k bulb. Her 4 other siblings are already well on their 3rd nodes, but she has been struggling along. Any information would be a tremendous help. Thanks in advance!
