Early this spring I built my first garden, the soil was miracle grow's vegetable soil. The plants in the raised beds( more like floating! The beds are 8x4 and are made out of concrete or something, and some are on sawhorses others on railroad ties.) flourished and produced well except for the watermelons having some disease ect. Now nothing is growing!!!!! I planted lettuce, mustard, and carrot last month! They are tiny not even an 2" in diameter! earlier this season I mulched with hay, and on the tomatoes bed added a lot of lime( blossom end rot) . The potatoes are about a foot high but not thriving( fall potatoes). I added more lime to the beds to fix any calcium malnutrition, got Jobe's organic fertilizer(4-4-4) which contains calcium! I have planted seedlings from the store and planted them, and they haven't grown much! And a cauliflower now has purple rimming! In the potato bed a tomato volunteer popped up, and it's stem was purple! phosphorus!!!! HELP PLEASE!!!!!!!!!!
