ppm TDS
Algeria_cannabisstarted grow question 3 years ago
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 🤙

Buon giorno weed doctors, please help understand the issue, maybe smb has seen this before. I lost two seeds of the same cultivar to the same symptoms...TYTwo seeds, same cultivar, 1 week difference, both pop neck bended with white woody spot at the base of one of the cotyledons. Doesn't spray the leaves, the membrane wasn;'t getting off w/o help. And I know it's not substrate - 2 other breeders germinated 100% and look healthy. TYSetup. Strain - Autoflowering
