I began to feed the girls once a week with molasses but it's too early to evaluate results. What I can say about molasses is that it's very sticky, super dense and quite tricky to mix with water.
Plant #5 looks drinking less water the the other sisters, in fact the soil is less dry the the other and the pot is heavier. Apart from that plant is growing happily.
