ph question

i noticed some necrosis in my leaves i knew this was a ph issue so i tested my water with the nutes in it ( mollasses,jamaican bat guano) and it was low it was around 6 and so i upped the ph to 6.5. but i didnt notice any difference the necrosis got worse so i tested the ph of the soil and found it was super low at 5 i was wondering how to change the ph of the soil?

Injured leaves won't get better. They will only get worse (even if you fix the problem). Its the unharmed leaves and new leaves that you want to pay attention to. To up the ph, try 1 tbl spoon of Dolomite lime per gallon of water.
