@Humboldt_Seed_Organisation_Seed_Organisation, I think you got the numbers wrong.

"Going of the ppm pen that would make your ec around 0.4ec which is low and I would indeed this up to 1200ppm ✌️ or 0.6ec 👊"
0.6 EC is 300 ppm (500) or 420 ppm (700).
2.4EC is 1200 ppm (500 CONV) or 1680 ppm (700 conversion table).
