How do these nutes look for vegging?

I just picked up some Miracle Grow Organic Choice Plant food with a npk of 7-1-2. How much should i try adding to my plants of 5 weeks old. I have some other nutes with npk of 3-3-3 that im feeding them already but how much of this should i sprinkle on top or mix in water im pretty lost on this subject?

Check the instructions on your plant food. You picked up a pretty mild food, so I wouldn't worry too much about burning your plants. I would still start with half-strength at first, though, and see how your plants react. Then progress to full-strength via the instructions! Good luck!

well it said 3/4 cup of nutes per gallon of water if that sounds right and i have a 2 quart container so i put 1 and a half scoops with a 1/8 scooper im pretty sure i did the math right..hopefully ha
