Question on fertilizing: I have Superthrive’s 9-3-6 liquid fertilizer that I use every 4-6 weeks for most plants. I’ve been following the recommended 1/4 teaspoon/gallon dosage for most plants, but then I asked chat and it said I should use about 25 drops per 4 cups?? For the record I haven’t been seeing crazy new growth at all. What do you recommend?
