Fox Farms has done most of the leg work for us. The only devation I use is I only use water for the first week after germination. Then I follow the schedule they recommend until I decide to flower.
During flower follow the instructions provided by Fox Farms. I have found out the hard way not to over feed with the solubles. Plus I only use the lower ratio of 1/4 teaspoon of the solubles EVERY OTHER WATERING.
The last week to 10 days of flowering I use water mixed with 1 tablespoon of molasses per gallon. I hope this helps.
