Platinum Blend is all I ever used by CoM, used to be Growers Choice or something like that. Designed specifically for weed. I always got the stripped leaves thing with that soil too. Epsom salt used to take care of that.Their Platinum Blend is a much better soil. Not every vendor has it. Every bag I've opened has live worms in it.
I soak mosquito bits in water and pour about a quart into each bag and reseal it. I usually buy soil a few weeks ahead.
HF used to be good soil, but lately its mostly ground wood that hasn't aged enough. It always had a Mg def at beginning of flower.
