flower nutes from chain store will it kill them

i purchased a box of KGROW today on impulse then realized i better not even think of using it till i run it by you guys.......

the 3 numbers on the front are 15-30-15 this will be for flowering

what is in it
total nitrogen 15%
5.7% ammoniacal nitrogen
9.3% urea nitrogen
available phosphate (p2o5) 30%
soluble potash (k2O) 15%
boron .02%
copper .07%
iron (chelated iron) .15%
manganese .05%
molybdenum .0005%
zinc .06%

anyhow as i explained before i live in the middle of nowhere so no grow shops within 100 miles i would bet and getting things thru the mail is basically no go cause its a small town with a very snoopy mail man.....he commented when i got a letter from amsterdam"seeds" wow you got a letter all the way from and looked at me all suspicous small town crap anyhow so getting 10 gallons of big bud bloom buster thru the mail is out of the question.......anyhow as im sure all you did at one time..this is first grow and im learning as i go so far so good

one more item i bought i think is a dud and will probably throw away its PH minus for pools active ingredient is (SODIUM BISULFATE) I didnt know that was bad I came home from shopping looked it up and some people say it will kill plants
anyhow once i get one good grow i will be at least sorta set

one last product i got today was garden safe fruit and vegitable insect killer active ingredient pyrethrin and piperonyl butoxide i dont know what that is but ive read its ok to use on plants..........please let me know if any of these are red flag no nos again this is a first try

thanks again for all your help ......hopefully once i get this rolling i wont be so high maintanance

those nutes will work. i'd start at half strength until you see how your plants react.

the bug spray is ok as well. if you have bugs.

I use those same cheapo gritty nutes that you mix into the water.

I use 30-10-10 for veg.

I'm saving 10-54-10 for flowering (coming up soon!).

I have the 17-19-29 just in case I want to boost potassium for some strange reason.

I have empty half gallon milk jugs that I use. I add 1/4 to 1/8 teaspoon nutes then fill it up with water. Works great! Just make sure to dilute it pretty well.

i didnt read your post but i bought this to a month ago and it works great. but im using fox farm as well ill read it....
