i had the same issue with mine..i dont have the one you have..something i was able to pick up at lowes/walmart (miracle gro blooming houseplant food..i think the ratio is .5-1-.5). I got brave and used as directed for a gallon of water..with superthrive..which was enough to fill all of my av's..so far nothing catastrophic ..I believe irina has mentioned how much to use..but whenever I try to go find it in a post..i cant lol..so..i'm curious to know this answer too

I use this food at 1/8th tsp per gallon and I wick water.

I am siding with Terrilou. I would use 1/8 of a teaspoon. In humid climate - you do not lose so much water to evaporation - so you can use 1/4 of a teaspoon per gallon on adults, and 1/8 of a teaspoon for starters.

Good stuff, by the way.

Great. Thats what I needed. I really don't care for the idea of having to have two more gallon jugs around here though. One for starters and one for adults. I guess Ill have to find a happy medium point that works.

Not to mention, the lady I pay to babysit my plants when Im gone will never get it right if I have two different mix ratios.

You will find the concentration that works for you. I use the 1/8th on all my indoor plants, young or old. Sometimes the tsp is level, other times heaping so there is a bit of variation. One jug for all.

My kind of system!
