Hi folks, i recently bought an EC pen, but i'm still not sure what values of ppm should i put in my plants.Since i'm growing in soil 2 plants 25 days old, that's what i found on the internet: Seedling : 0.8 - 1.3 EC
Vegetative : 1.3 - 1.8 EC
Flowering : 1.2 - 2.0 EC

So, according to what i've found i should stay around 650 and 900 (1.3 - 1.8EC) of ppm right?
Cause i've been staying below 600 since the start.
Also i don't know if i should use RO water or my tap water with 300 ppm.
From what i've heard with RO water (0 ppm) i should be able to add more nutrients in the solution right?
Cause i'll experience nutrient burns, if i go over the max ppm for vegetative stage, which is 900 ppm right?
right?
maybe i've answered all my questions by myself xd

if you use ro water add 150 ml of cal mag first then adjust for rest of nutes,if your tap water is 300 you could diliute it with ro water and not add the cal mag
