When should I start dropping rh and how much too. Dont want to go too low incase it stops that co2 uptake but I am worried about mould.

Hello you can drop the RH down to about 55% to 60% would be fine. Co2 is not effected by RH its temp that makes the diff with co2

I thought if the rh was wrong the buds close up and can't obsorb it co2

It's not the relative humidity you should be looking at, but the VPD. You can have plants growing in full veg/early flower @70% humidity provided that the temperature is high enough.
When the plants are young you need a low VPD (0.70 - 0.85) and when they are flowering you'll need a higher VPD (1.2 - 1.4). In the chart provided you'll see the value's you should aim at. I don't know how old they are, but they seem in early flowering. So your VPD should be around 1.00. If you check the chart that could be all sorts of different combinations. I vaguely remember you saying your temps where around 28°C, so yeah...Your humidity should be at 70%.
It's science folks!! Can't argue with that

Hello its the leaves that obsorb co2 not buds

Temps have dropped to around 25 so by vpd 60'-65. I've upped my heater to hopefully control temp and vpd abit more accurately. The humidity is getting above 70 because we've had alot of rain and fog. So I've upped the temp other heater because the fan keeps sucking all the humidity out heat with it

Morning feed as I didn't get a chance to get to the tent last night. Still have to seal the external window up to stop external moisture in, will probably just be cardboard with a hole in it to let the inline fan vent.

Not much change. Blocking my window off tomorrow to stop the humidity issue and seal off my "lung room". Added some mega pk13/14 into the mix and hopefully will see some results soon. Day 45
