growing in normal garden soil mixed with fertilizer.
the ones in the trays are fertilizer mixed with potting soil. potting soil obtained from some street vendor.
the fertilizer is this one : Gromor Compost - Fertilizer - Gromor - KwaZulu-Natal

temperatures day time: 24 degree Celsius and night 8

Night time temps to low,and the one in the big pot is showing classic signs of nutrient burn as in too much. Cant you take them in at night and put out in morning? regards
