Hey I'm running heavy 16 full line and I want to also add in PowerSi. Growing in soil and using RO water. When I put the power si in the water in lowers the ph down to about 4.0. Wondering if I should bring the ph up after I add the powerSi and then proceed with the heavy16 nutrients. According to their feed chart if you use the prime and clean water there is no need to adjust the ph.
