you will see that the % of each part is stated.
Such as 20:20:20. This means 20% N, 20% P, 20%
K. The remaining 40% is just other elements
that make-up the soil. In liquid it would
usually be water. This ratio can change between
different types of nutrient and soil brands so
we need to understand what Cannabis likes.
Cannabis plants like good levels of N and a
normal level of P and K during vegetative
growth. You need to pick a bag that has all
three, not just 10:20:0. When looking at
chemical fertilizers you need a mixture that
has the first number higher or equal to the
rest. 12- 12 - 12 is fine, 20- 20 - 20 is fine, 12- 6 -
6 is fine and 18 - 4 - 5 is fine. The 12- 12 - 12 and
20 - 20 - 20 are the best ones to find. Something
like 8- 20 - 20 is not suitable for vegetative
growth. Bags with higher P are for flowering
plants. As a grower we do not transplant to new
soil for flowering. We simply use plant feeds
to bring up the P levels during flowering.

Try to find a soil that is not too moist.
In other words try to find a soil that dries
out well and does not hold water like mud. It
