can we use full words on here? 'k', 'u', 'wana', 'y', and 'de', are hard to read.

Also, Potassium Sulphate has a pka of 7. Not a pH of 7. Potassium Sulphate will generally lower pH towards 6.

well to bring up your potassium without affecting your ph ill suggest using potassium sulfate. it must be atlest 1.5 times your nitrates. everything is modeled around nitrates cus its literally the building blocks of all matter i.e. proteins. so try that. but one thing to note not many crops can be grown at those levels of Na and Cl especially water crops like cucumber and watermellons. there is no physic difference in a plant grown in soil compared to soil less media. all that different is nutrients availability and contact time with roots

Potassium Sulphate, Sulphate will lower PH Sulphuric Acid.


no it wouldn't.. it isnt the sulphate that lowers pH. it is the free H+ ions that disassociate for acids or acidic salts. mineral sulphur is different than sulfate. mineral sulphur reacts with OH radical with water to oxidize itself into sulfate. this process removes 'O' oxygen ions and leaves free H+ ion which interns lower the media pH.

Please, can we stop this ridiculous amount of bottom posting! It's poor forum etiquette, and a PITA to read through. Moderators?

Yea I dont think we need to quote and re-quote repetitively in replies please, its getting ugly and difficult to understand. A simple reply post is all that is required.
