Fast buds 20/21

Every strain is different. All you can do is make sure your substrate levels are right. Mainly ph and proper nutrition. If your soil ph is borderline it can slow growth. Plant can't absorb nutrients as easily. Around a 6.2 in soil is ideal. This needs to be tested by testing run off ph after watering with a calibrated tool. I don't see what your ph going in is on dairy or I missed it. I would start there. If you need more assistance and choose my answer feel free to message me. Good luck and happy growing. 🌲🌲🌲👊
