Lemon AK Auto Fast Buds Indoor Grow

One plant started to flower, the other seems to be a bit behind in development. The one which is developing slower was the one that was germinated in a jiffy instead of the soil and which is receiving nutrients. It has a lower height and less developed buds. On the upside, it has ca. 10 headbuds instead of 6. I put it on a stand to have both plants receive the same amount of light. Watering, nutrients, etc. same as last week.
