I have an auto about to flip to flower and 3 photos still in veg stage. How should I handle the humidity levels? My understanding is that the RH should be reduced to ~40% for my auto in the process of flipping to flower but I don’t want to hurt my other photos.
Any tips for keeping all plants happy in one grow tent?
How are you flipping an auto to flower?
Right, this is automatically done by the auto flower but I have adjusted the lighting to 18/6 and next week plan to use jack’s blooming nutes when watering. I’ve ensured that the lighting is 18-30 inches north. I want to decrease the humidity in the tent but concerned 40% will impact the photo plants.
These gals have been thriving and it’s a struggle some days to get the humidity above 20ish on no water/feed days. Highs in the 40’s on those days. You’ll be good.
My flowering tents often hit 65% RH, keep the air moving inside the grow space 
AT flip is not the time to switch from 65-70 to bam 40%
High humidity will be beneficial during the stretch 60% is not going to be a problem with good airflow.
Once pistles start to form up we reduce humidity to keep buds clean and free of mold.
Like everything with plants gradual changes help with acclimating the plant to the new environment.
As @OGIncognito saying just keep air moving no matter the humidity it will be fine just keep it moving happy growing my friend
