So I haven't really dosed before and I want to do some DIY ferts, I found this recipe online and am not sure whether it's any good or not and I figure that someone with more knowledge than me would know. Here it is:
Mix three cups of water with:
1/4 cup potassium sulfate
1/4 cup epsom salt
1/8 cup Potassium nitrate (salt Peter)
Add 1 tsp for every 5 gallons water
Also add 2 tsps of calcium carbonate for every 10 gallons water
Any thoughts? Thanks!
