Hey, F2H
I have the same grow going that started on the same day. 5 feminised BM in soil, 3 with seed leafs and two lagging. This is my first grow so I'm glad I found this thread, it looks helpful. I'm subscribed.
I read the lights should be 12" away. I started mine about 4" away and the seedlings squated. When the lights were moved to around 12" the seedlings began to stretch and reach for the light. Now I keep the light to where the largest seedling looks like it is still reaching for the light, which is about 12". Then again your seedlings look better than mine.
