looking great [emoji106] a few hiccups but we all have them from time to time.
the when and how much to water is a tricky one to explain,its more a feeling.a spare dry pot in the corner as a gauge.depends how fluffy soil is/temps/humidty/fans allsorts.
not much more than 3 splashes 1st week maybe 4 drinks of 250ml 2nd week,upto about 1250ml daily in my 6L fluffy soil pots.
soil does buffer ph to a degree,maybe a natural ph upper ? is it baking powder or baking soda or one of them type things do the trick.
