Hi buddy, I read your diary. Yup, she's topped perfectly. You took her early enough that it'll have an impact on the other nodes but you also let them, the 5th develop fully and then take the 6th after a few days of it been shown 👍. As for the RH, you are using a tent right? If you set up your extraction/intake fan and run it for 15mins you'll be able to keep a high RH. I don't like using De/huimifiers in tents. Yoi can get yoit RH high enough by just having your tent sealed up and after 2 or 3 days of your grow room where the tent is, if you keep that door closed the RH will go up to 60% and intake/Extraction fan will draw in the rooms RH into the tent. Also you can either hang a damp towel or lay it on the floor beside the pots. Doing all this will hold a steady RH, cause if it's jumping up and down, then we'll, yeah.
And then when it moves into flowering you can set the intake/Extraction at 100% of the time and it'll bring your RH with it 3% of your grow room if not the same, just open your grow room door and leave it open and it'll bring the RH down to your houses which is normally 40-60% depending where you live, then run a dehumidifier or not, it doesn't sound like you have high RH where u live if you need a humidifier. But these things will hold a stable RH.
RH climbs quickly in tent like 10-20% with a few plants with in mins the temp is slower so you can run the intake/Extraction on a timer 9nce you know how long it'll take the temp to reach undesired range. RH can be as high as 70-80in veg and it'll go that high by doing this.
Good luck, feel free 2 DM me if u need 2.
