First indoor LED & auto grow bp1500

Day 50 things are chugging along nicely, buds and tricomes are stacking up, run off is continuing to come out 6.3-6.5, dropped 1 gram of nutrient powder but tips are still bunning will drop 1 more gram, box recommends 5 gram per 5 liter I'm mixing at 5 gram per 9 liters so will drop to 4 gram, kush n cheese are further along so guessing they will finish first
