@smokeyfromau Limited morning sun , full sun from about 11 am till 5 pm . I got 4 females out of 6 plants , If I get some seeds from her you can have some to play with .
Reference for me . Interaction between uptake of calcium and phosphate
A model describing the interation between these two nutrients on the basis of root respiration, ion affinities and the precipitation of calciumphosphates in the immediate proximity of the roots is proposed. During root respiration hydrogencarbonate ions tend to keep calcium ions away from the root growing points. Uptake and translocation of phosphate from the soil to the growing points secures the uptake and supply of calcium. Accumulation of calcium ions at root surfaces may precipitate phosphates and thereby hinder uptake of not only phosphate but also of calcium for a short time. The consequences of this sequence may be very pronounced because calcium is not retranslocated in plants.
