seeds

[carz]

when you buy seeds from a seed company do you get literature that says what ppm to use per stage of growth according to strain?

no..

Nah, it doesn't matter.

Here's what I prefer

seedling - 200ppm

small plant - 400ppm

12" high - 500ppm

12" - 24" - 700ppm

then flower

week 1-3 - 700ppm, still grow nutrient
week 4-5 - 1000ppm, bloom nutrient
week 6-10 - 1200-1400ppm, bloom nutrient. Or for safety, just keep on 1000ppm
week 10-14 - flush solution

Too little nutrient is better than too much.
