Hello! How to dose pottasium after initial source of pottasium is used? Can I dose the Muriate of potash that 100% water soluble? I read somewhere that we need to dose liguid dosage of Potassium (KH2PO4). What is the difference?

I'm finding hard to get red clay. Can I use gray clay which is available easily for me? Does that contain iron? Or can I use red soil (mix with little clay) that's commonly available in India? Is that one are you referring to laterite?
