cannabis environment schedule

This is how I have come to do it. Take what is useful for you and disregard what is not.(BL) Correct me where I am wrong so I can be better. This is based on hybrid genetics flowering time 8-9 weeks in a soil garden. Adjustments must be made to each strain as timing is different for each.

flower start
day: 65% rh 78'f
night: same

I trellis and train everyday for first two weeks to scrog, super cropping can be done here as well. (pinching the stems to stress)

week 2
day: 60% rh 78'
night: same

stop training and hang high trellis. I let the flower sites extend up here bc the trellis is full. They usually only stretch another 12" so it gives me a great canopy zone full of bud sites.

week 3
day: 60% rh 78'
night: same

Prune all lower bud sites and excess growth under the first screen. Use scissors. This is deigned to be performed after stretch is has slowed and bud site formation is most important to the plant. I top feed here.

week 5
day: 55% rh 77'
night: lights out lower temp to 67' for an hour. I raise temp incrementally throughout the day until two hours before lights on; back to 75'. Note: don't overwork your AC in hot months. The temp can come back up after the initial hour of two of cold at light out. The AC right at lights out also helps fight increasing rh.
I top feed again here. secondary nutrients, lightly and as needed.

week 6
day: 50% rh, 77'
night: same schedule as above
open flowers and check for any signs of mold. pay close attention to night time humidity spike. Watering slows down to every third day/ as needed.

week 7
day: 50% rh, 76''
night: 70'-75'
Lower light intensity

continue until harvest.
hang dry 50%rh 68' 7-10 days, cure

Just rough guide to follow if you didn't have one. This schedule is bring color out of the flowers. It works well for me, but things can always improve. I'm prob off on some ideal numbers here, maybe someone has the vpd chart they can add. Hope this helps someone.
