Houston, we have a problem. Dosage for SuperThrive is 1 drop per gallon. I checked using a liquid of similar viscosity to ST and found that 40 drops made up to 1mL. There are almost 5mL in one teaspoon, so you are using TWO HUNDRED TIMES the recommended dosage. Hence the extremely soft-looking, dull, intensely-green leaves with burnt tips. Nitrogen toxicity.

FLUSH FLUSH FLUSH and lay off the Superthrive!
