I love this stuff and use it in varying strengths from start to finish. I use good organic soil and fish emulusion and that is about it these days. I used it years ago and somehow or another had gotten away from it in recent years because I moved to Costa Rica and it was all most impossible to find. About 3 months ago a local ag store added it to their line up and I started a whole new program using next to the method had been using the past 4 years. The difference is remarkable IMHO. I start the plants off at 1/8 strength label directions at 2 weeks from seed and 3 from clone. I feed them once a week for 2 to 3 weeks depends on how the plants look, then increase to 1/4 strength the next feeding and half strength until 1/2 way through flower and then back down to 1/4 strength until about one week to harvest.
Good Luck growing and Merry Christmas
