Thats a pretty vague question. Is there no mixing instructions? If there isn't perhaps google. Also is it a bloom (flowering) fertilizer? It sounds like its a veg mix due to it being 20/20/20.

that sounds like fertillizer that a farmer would use for corn or other crops not for a plant in flowering but if thats the only thing you have now or money for i would go a tsp to a gallon first later you can increase it if needed but if you burn them it could be all over soon start out with a little first

There are people who use Jack's Classic 20-20-20 throughout an entire grow very succesfully.

OP. I use a tbl spoon per 1 3/4 a gallon of water. I start out with half a tbl spoon at first before using the full tbl spoon. I run 3 gallon smart pots. Last run I netted a QP under 250W HID from one plant. Good Luck and Happy Growing!

Read the instructions on the nute box and cut the number in half. If it calls for 2 tsp/gal use one. Watch your plants and see how they do at 1/2 power. If they seem to thrive go ahead and kick it up to 100% package advice. BigSteve.
