neptune harvest is the best stuff you can buy, i got some a few weeks ago to try it out and have fed my plants with every water to see if this will burn them and they look better than any grow i have ever done.

i started by using just a 1/4 of what the directions say per gallon the first few times and now they are taking it at 3/4 strength no problem, plus its alot harder to nute burn with organics.....smell like ass though
