Before placing the seeds in the soil, I washed the soil and measured the percentage of salts in the water leaving the bottom of the pot with a TDS device
Question: What is the normal rate of salt in the soil before planting ?
You know that the first 3 weeks you need around 500 ppm drain, so you should check what comes out to know what to put into the soil, if 100 comes out you need +400ppm of nutrients and check again what comes out when you watered your plants, the 500 need to increase a bit week by week until you reach around 800 before switching to flower
Who knows man it’s not just salt that it measures.
TDS means total dissolved solids.
I don’t think you should have to was your soil before planting.
So for a seed you shouldn’t need much nutrients in soil to get it going.
I say just plant your seed and enjoy the ride friend 🤙
