Fullgas

Having issues getting the plant to feed down to cold outside temps had to install an external heat source to keep inlet air at an abient temperature I've made up a spray feed with microbial foliar spray, had a few issues with ph and lockout aswell so flushed and reset with the feed and gave a higher pH than I'd usually give of 6.8 my run off is now sat at 5.8 which is in range with the plant magic guidelines but I still want to raise it to approx 6.2
