My run off is measuring 4.5-5.0.I’m using black gold all purpose I think it’s been acidic out of bag.I retested some fresh out of bag its run off was also 5.0 using water with ph of 7.0.My seed mix run off stays at 7.0.
What can I add to water to slowly bring up ph during flowering?What about ashes from cured red oak?
I’m getting sporatic growth.It seems right before I water.I’m not sure if it’s because ph drops when soil is drier??The old growth is dark green while new growth looks great.
I added ag lime to the mix in storage bin.It’s same soil.Will ag lime raise the ph of the soil in my storage bin?Does ag lime just neutralize acidic soil or does it keep raising ph levels if too much is used?
