What strain of autos are you growing? What kind of medium are you using? e.g., soil, hydro, whatever. Indoors or outdoors? What size pots? Got any pics?
As a general rule, autos are sensitive to nutes. Do not feed autos according to a schedule put out by Fox Farms, as autos are not what that schedule was intended for. I use Fox Farms products on my autos, but I don't try or even need to have it down to some kind of exact science. Your plants should be flowering by now. They only need Big Bloom. I've never used Grow Big on any of my autos.
I use both Big Bloom and Tiger Bloom every other feeding, but I've also done just fine with only the Big Bloom. The plant is what it is. You can't turn it into a super plant by adding nutrients, rather you will just keep it healthy and doing what it is genetically predisposed to do.
Look at the back of the bottles for the directions. Big Bloom says 4 tablespoons per gallon, every other watering for "general feeding". That is too much. For your 1st feeding, just use 1 tablespoon per gallon, which is the dose it also recommends for seedlings. Tiger Bloom says 2 - 3 teaspoons per gallon every other watering - so just start out with 1 teaspoon for your first feeding.
Then watch and see how your plants react. They should be just fine. If the plants seem good with that, I would do the same thing for the next feeding. After that, they should be big enough to increase the dosage a bit if you want. Remember that autos are more sensitive to nutes than regular plants. You will never need to use more than 2 tablespoons of Big Bloom per gallon or 2 teaspoons of Tiger Bloom per gallon. Just keep an eye on your plants and adjust accordingly.
I've only been growing for 1 year, but I've never had a problem with nutes when it comes to my autos. Their lifecycle is so short it's hard to screw it up.
