my water source has a ph of 7.5 I know I need it to be lower. How much can I lower the ph from feeding to feeding? Could my next feeding be 6.5 if it has been 7.5 everytime before? I feel like it would shock my plant
there is a fairly fresh/clear running creek and some ponds around where i live. they have neutral ph levels. is it ok to use these water sources for an indoor grow?
