fertilizers 20-20-20

i got a box of mg 20-20-20 all pur plant food and i never used it yet my plants got a growth suprt so i didnt care about the fert. im using peat moss and pure cedar mulch in five gal grow bags and its been almost four weeks they are about eight or nine nodes up and i was wondering WHAT would this fert do for my plnat would the NODES stretch or stem thicken or WHAT? let me know what happened to yours when you fert and what you used and it would be very helpful no matter what

yea i would use them just dilute them 50% strength

aight ill do that then next week or two weeks form now up it to 75 then etc right k well im not sure if i want to use nutes but ill do it once and will see what they do in like five days
