Overfed, feed just water for at least the next couple of waterings. Only use the thrive alive during stressful situations like the day before transplanting or transporting plants. It's also good to use when the plants get stubborn. Don NOT use thrive alive or other superthrive like products regularly. Try not to use them at all during flower in fact.
