How Much Amendments Should I Add?

im going to mix my soil very soon but i need to know how much of my amendment i should add. I will have 15 plants growing in 5 gallon pots.

i have 2 bales of promix BX and 5 bags of black earth top soil to mix together.
I have Worm castings, high N bat guano, Bone meal, Dolomite Lime, to add aswell. Im going to use all the worm castings and bat guano but im unsure of how much bonemeal and Lime to add.

So how much bonemeal and dolomite should i add to each 5 gallon container?

+rep for speedy help

I'd use a cup of bonemeanl per 5 gallons soil and 1/2-1 cup dolomite per 5 gallons soil.They are organic so will not burn like chemicals. Is this your first time growing this strain, or is it a clone from a previous grow?

You have no K in that mix.

Kelp meal would be your best bet for K and trace. 1cup/cf

I would also add some more perlite with those EWC. They do make the mix heavy.

*I* do 2cups of bone/cf and 1cup of lime/cf

Easy way to measure: 1CuFt=~7.5 gallons, so 3-5 gallon buckets (15 gallons)=2 CuFt. So, 2 cups of lime, 4 cups of bone and 2 cups of kelp meal/15 gallons.

hey wet how much lime & perlite should i add for 25 gallons of soil mix

what is the best apparatus to measure?

Ya I would add either kelp or azomite. both can be found anywhere online. I would add 1/2 cup of bone meal and 1/4-1/2 cup lime per 5 gallon bin. Also need some kinda drainage help: perlite or pumice. Its usually easier to add all amendments to the soil first then put into containers.
