Soil Ph 5.4 and it was phed at 6.6

Yesterday top dressed with lime..Any suggestions? Thanks

You need to try and bring the ph up.

I watered it at 7.8 ph and the run off remained at 5.5. It's Weird because the other plant has the same runoff but its doing great. Hope the lime helps it.

Add some dolomite lime to your soil to bring the soil ph up

Yeah I added that seems to be okay now ty
