just changed out my fem. northern bright and rooted k2 clone with a 2.5/2.5/2.5 ml/gal and 1 tsp cannazym this morning. the NB are nearly 1 month old and look beautiful. i totally removed superthrive from my lineup up supplements. it always seemed to burn the tips of my leaves. i have had great results with the cannazym. hopefully in one more month the ladies will be ready to flower. have pics soon. peece and smoke
