  1. Is it safe to use this fertilizer 15-30-15 miracle gro beacuse my mom has extra around. If not what kind can i buy without having to buy multiple n-p-k formulas for each stage or huge bags of fert i dont need
  2. I bought a 1kg can of 20-20-20 fert wich is good for the vege stage for 7.50$ CAN ....when flowering stage comes... im gonna buy a 5-50-17 fert for probobly the same price...
  3. what is good for seedlings that r 2 days old
  4. dont even think about ferting seeds... u dont want to start using fertz until 3-4 weeks of vegetation have passed... or it could kill your plant... i also throw a little bit of salt into the water... about 1/2 teaspoons per litre...
