i have big bud powder and it clearly says .3 grams if u use a whole gram more the ur gonna have the classic case of nute burn for sure.
btw 7 grams for 5 gallon is wut it says
whiterhyno420 not trying to tell you your wrong but this is straight of of the AN site. Are you sure that it doesn't say something like .5 g/l.
The first is for moderate feeding and the second is for moderate heavy feeding. 3.8 L is 1 gallon and the big bud powder line shows 1.36g/gallon for moderate and 1.44g/gallon for moderate heavy.
If you don't drain every week you would just add the differance between the weeks. So 1.36g plus .23g equals 1.59g, and 1.59g is what is listed for the next week of feeding.
This is simply what their sight calculator says nothing more.
My package says:
1tsp=7 grams
add 10 grams per 20 liters
(1.5 tsp per 5 gallons) of nutrient solution in your reservior.
20 liters is aprox. 5.25 gallons, that would mean that the package says to use about 2 grams per gallon.
I found a pic of a label check it out. The label in the pic says to add .5g/liter. 3.8 times .5 equals 1.9 g/gallon.
In the end you have to do what you feel comfortable with. Hope this helps
