The girl is now tallest in the box, blooms, but has very few side branches. Rather, tp seems to have moved up after the transfer and the other branches are no longer catching up. However, the lower twigs have grown and the flowers are on them. But we have a long way to go.
She’s stacking up nice, hows your calcium uptake? Kelp will get those side branches growing outwards! Don’t give up and try different things! For the calcium, boil some eggs and add Magnesium sulphate or epsomsalt 5 tsp per gallon... She’s green so you nitrates are handled! Don’t give up!
