High PPMs???

Ok i used fox farm on my last grow and got some free organic nutes from hydro store,back said for soil 1-2 tsp per gallon so i went with 6 tsp of each Ca,Mg,and N for 5 gallons of water.I got a reading of 800+ so i added 2 more gallons and took down to 650+.Plants are bout month old, is this PPM reading too high for my kids?

yes, that is a good possibility, depends on the size of plants, overall health, and how rootbound you are.

Remember to start the food slow then work your way up to full strength as they need it.
