I’m growing in organic . Composted tree mulch etc as the base and then searles 5 in 1 . One third is the 5 in 1 and 2 thirds basic compost . With perlite for drainage . So I’m wondering …. Is there an issue with calcium and magnesium if I water with 0ppm rainwater or will it be fine ? And also I checked the runoff ph and it was 7.3 . How or do I need to get the ph down ?
Thanks hopefully hear back soon
