The wifey brought me a present. Its MG all purpose plant food. Shows a tomato in the Pic so I'm assuming I can use it on my plant. I know MG isn't the best but its what I got onhand. Using this for nitrogen in veg stage. It shows. 24 percent nitrogen, 8 percent phosphate, 16 percent soluble potash, .2 borough,.7 copper, 15 percent iron,.05 manganese, .0005 molybdenum and,.06 zinc

What's the best way of first introduction of these bytes? Half strength? Quarter strength?
