You need to get that down mate. 55% is the absolute max during flower. You'll need a dehumidifier to get it down. In the mean time make sure you have good air circulation.
Did you put the probe in with the buds or did you read th RH from elsewhere?

Now there's a question lol. Very much debated tbh. Most experienced growers aim for around 40% during flower. Imo that's for a few reasons. 1, to get the plants to drink as much from the medium as possible rather than via the leaves due to high RH. 2 to help reduce the risk of bacteria growing(budrot), arid dry temps kill lots of bacteria.
The latest discussion is about how high or low RH effects the trichome production. Many people say lower humidity creates stronger and fuller trichomes but it's very hard to prove either way.
I've had low 20'sRH in flower before but I couldn't tell you if that had an effect on trichome production because of all the other elements to factor in as well
For me, 40% is the sweet spot but 10% either way is not an issue. Over 50% and up to 55% I'd be concerned but with good air circulation that should be ok. Over 55% and I'd be shitting bricks😉

Its Thermo and Hydro DC102 that i ordered after reading a post on here saying you can buy them, its from China about a week to arrive.
28c/62% no fan
25.6c/49% with fan
I turn the fan off on a night although i've been told to keep it running but had bad results makes plant droop. I would assume humidity might go a bit wild then with light off? I'll put a few pictures up later this evening. Thanks, got it, under 55%. Now under 55% Fan Air circulation.
Best thing to do until the dehumidifier arrives is to have your fans running 24 hours and add a heater/oil rad to come on when lights go out.
Sounds like your lights turn off and the drop in temp will raise the humidity over 62%. The dropping is probably down to the cold temps when lights are off. Adding a heater for lights off will raise temps giving you a lower RH and stop the droop.
Even if your temps go up to 30/31 lights off its better than budrot.
I started using LEDs recently and I had lights on at night and lights off during the day. Lights on temps 27/28, lights off temps 29/30. Even if it's warmer at the plants night time it's still better than high RH.😉
