Bottle instructions assume it's being used as a stand-alone nutrient. The website assumes you are using the Trio.

The Weekly Feeding Schedule is just that...a weekly feeding schedule.
The numbers on the left represent the week since germination. (the plant's age) Follow along that weeks 'line' and that's what you should be giving that week. Not daily...not every other day, but once a week. If you need to water inbetween, use plain, properly ph'd water. Ingoing water ph in soil or potting soil mix, should be between 6.3 and 6.8'ish. I tend tword the high side, (6.8'ish) because nutrients bring the ph down, and eventually the buffers in the soil will fade, and lower the ph too.

Don't bother with the soluables till you get the hang of feedings and waterings and troubleshooting your plants ailments. It's a bitch to use, and will easily destroy a crop if mis-used.

Mix only as much as you'll need that day. The instructions I gave were to help you avoid mixing too much at a time and letting it spoil. Use leftovers on your houseplants. During the summer I make 3 gallon batches. Right now though, I get by with 2 gallon batches.

I live in the desert and flower in an outdoor shed. Since giving heavy doses stresses my already heat-stressed ladies, I give 1/2 doses, twice a week. Likely you won't need to do this, but I offered it as an option to show the flexibility of Fox Farms. If you have normal operating temps, stick with the website info.

Cannabis prefers a wet-dry cycle. Overwatering will cause major problems like nutrient lockout, root rot, death.

Monthly flush to release salt build-up. I flush on the first feeding day of the month. Easy to remember.

If you only need a quart, no sense in mixing a gallon.

Did I miss anyone...?
