That's one of the biggest problems with soil. You are not supposed to feed plants until flower in theory. That's why people use coco or soil less mediums. So you can give your plants exactly what hey need and nothing more. I use ff happy frog soil and its very hot for seedling. Once they got used to it they grow like crazy and only need calmag right till flush. Then he soil will be way lighter. Try to mix with perlite. Or vermiculite. Or even plain coco. Diluting soil for seedlings is a common practice. I've seen he grow boss and he try's to sell the idea of a "magic formula" which does not exist. So don't worry much about following the recipe but to understand what and why he is doin. Here is some info on ppm so you can understand better. There are several scales used by nutrients manufacturers and meters manufacturers.
its all about EC

It's hard to say not knowing ur strain and how old it is I just followed the fox farm chart of nutrients, but I have learned by adding 2tablespoons of molasses I got a slight case of iron toxicity. I'm also on well water I dnt know the ppm of iron in the waterComment
