swamp weed ph question

Posted this in general grow but i guess it sould be here.Water ph 5 soil ph 5.5 could this be done.options ive come up with could be (1)use alkaline fertilizers. (2)raise the soil ph to 7.5 to compinsate. (3)flood the soil with lime water every 6 weeks. (4)is there a very slow relese form of lime say(lime rock) that would not get leached away. last swamp grow had same soil ph but the water ph was one point higher that went fine.Is this ph problem beatable or is the water ph of 5 just pushing it any thoughts from other swamp growers would be very much apreaciated.

you could try all that but your bet bet would be to just use buckets with your own mixture. however swamps are tricky anyway because of all the moisture and damp air, it's got a high chance of bud rot/mold. not to mention they're real buggy.
