First time grower 6 week old Kushage plants

First time grower, first timer posting here also. I started my grow late febuary. I ordered a kushage seed online I started it off in rockwool then moved it under a 250 W HPS in my closet. It worked great. I also used FoxFarm Grow big. At about 3 weeks I cloned my plant at about 15in. Then again at about 20in. I used rockwool a Humidity Dome a seedling heat pad and some shruttz root hormone powder. I had a 100% success rate. Currently the first plant is almost 3 ft and the first 2 clones are 1ft so i moved them under a 600 watt hps in a cool tube for flowering. All the flowering plants are in 5 Gal smart pots. The reason for the post is to get feedback as I am really in the dark about what to exspect. I have gotten this far by simply online researching, and have read alot of information about flowering cannabis but it is my first time so i really dont know what to exspect. Any feedback, tips,or criticism is welcomed thanks

Any specific concerns you have about flowering?

smell for one also how long it will take to bud the info about the strain says anywhere from 60-66 but im wondering if it could be done earlier. Ive just never flowered a plant indoors before so its new to me
