Strengths:
Marijuana cultivators have found that full
strength nutrient solutions are not a good
thing. In fact even medium strength formulas
have the power to burn your plants. Consult the
information on the packs, but in general 3.5
mls of A and B and C per litre is usually
called 100% strength. The same amount mixed
with 2 litres of water is 50% strength.
Marijuana can grow very well between 30% and
50%. Never go full strength with your nutrients
if this is your first time. Try 30% for the
first attempt and see how your plants do. You
will be surprised at how rich a bud content you
will produce with this amount of nutrients. The
most common problem associated with hydroponics
is plant burns. I have rarely heard of someone
under-feeding his or her plants in a hydro
system. I have heard plenty of reports about
overfeeding plants in hydro systems. Over time
you will get to know your strain and what it
likes. The better you know your strain the
better you will be able to control your feeding
amounts.
