Jury is still out on the auto-flower varieties, or at least this specific strain. DLF-3 has small buds with a lot of red hairs - I'm hoping she plumps up in the next week. DLF-4 is covered in crystals, looks like she was dipped in sugar. Be interesting to see what happens over the next week.
I'm no pro, but it looks like your ladies are looking for more light. Stretching a little much, pull that light down a few more inches for more bud, or add another light :)
