My question is:
Whats happening to the microbes as they decompose? (we add them every 3 days)
We've been seeing really low ph in the buckets on the ends of our feed lines, which has caused yellowing and it is slowly creeping its way back down the lines towards the main. 4 out of 5 plants in each line are doing great.
The ph was too low in the buckets that had yellowing (under 5.0)...we imagine it was a ph lockout (cal+mag) so we drained the system and added fresh nutes and tea. We always swing our rez ph over the week from 5.5 to 6.5, confused as to how the ph is dropping off so low in the end buckets.
This led us to wonder if the decomposing microbes are contributing to a dropping ph as they die off yet remain in the system?
20 x 5gal dwc buckets organized in 4 lines of 5 buckets on 30in centers. Fed by 100gal res. gh expert formula nutes, adding ewc tea every 3 days at one cup per 10 gal. 6k HPS overhead.
