Growing in soil, Regular Happy Frog, nothing added (other what was already in the bag) and the PH runoff is low. Does PH runoff really matter? It’s super low like 4.5! My water in is filtered and 6.5. I just adjusted it to 6.5 late last week after discovering this. Originally 6.0

That number does really matter! Low runoff pH usually comes from 3 things: One is microbial growth in the substrate. This growth can come from beneficial bacteria and fungi as well as serious problems like root diseases. ... The second reason for low pH is your plants are favoring cations over anions. Your plant looks good—- I’m going to guess it’s 1 or 3— all good.
