Thanks :thumbsup::thumbsup::thumbsup:I was cosidering to add calcium but was not sure if the deficiency was because of lock out of nutes and did not want to make the problem worse. I aslo thought spraying with balanced fertilizer would be enough.but i now see it didnt have any calcium! The EC of the nute spray was 1.4 EC maybe it was a bit strong?
With regard to the rain water its Ph is 7.0-7.1 with an ec of 0.10 so not much disolved salts.
In the summer when I run out of rain water i get a truck full of well/ground water EC 0.9
Could also do with some advise on watering frequency
:thumbsup:
