Do you use any bloom nutrients terpene?
I use Botanicare's pure bloom soil mix. Usually I eyeball about 1/3-1/4 of the recommended dose. I only do this when the plants start looking light in color. It should probably also be mentioned that certain Ace lines are light in color anyway, so baby steps with the feeding. I also like to foliar with epsom salt (about 1 tsp in a liter) when the plants show magnesium deficiency.
Past that, my super simple soil mix:
Fox Farm Happy Frog
Earthworm Castings
Rock Dust
Dolomite Lime
I only started adding the rock dust recently because of how much bigger I've started vegging plants. My stems are about thumb thickness in a 3.5 gallon pot instead of a 10 gallon pot like I used to.
I grabbed my old Hanna meter from back in the hydro days to see exactly what the nutrient value of the water was. I was hovering at 800ppm (1.6EC) in the bottom of the Purple Haze Malawi x Napalm bucket, but decided to start with a fresh mix of 1000ppm (2.0EC). My "mix" was tap water with botanicare bloom and a dash of epsom salt.
I figure thats about as hard as it needs to be pushed, but we'll see in the coming weeks.
