help me fill my water tank with nutes

i have to leave my plant for a 10 days so i decided to make a 15 lit water tank.my plant is in a soilees mix and i want to add nutes in the water .so how many ppm i need in my water for watering my plant every 2 days.I'm currently in 40 days veg and every third watering i give them about 600-800 ppm (measured with the water)nutes.

yes but once every 3 watering.....now if i use 800 ppm every time i water it i will burn it is it right?

Just feed them 1000-1200ppm every 3rd watering
