Hey @Naughty.Psychonaut
Thank you kindly for the welcome and for taking the time to assist with this mystery. I'm hoping that the pic might answer some of your questions and further assist with a diagnosis.
The GC clone on the right is the only one that looks a bit wet as I thought that the soil might be too dry and watered yesterday. I left the other 2 clones as is but 24hrs later they all look the same so water doesn't seem to be the issue.
I'm using Freedom Farms soil, haven't started nutes yet, wanted them to settle in first, watering lightly with a spray bottle every 2 to 3 days, only water when soil is dry, ph is 6.9. As mentioned, they were doing well, nice open canopy as opposed to the now droopy, wilty profile.
These last few days have been cold, I don't have an aircon but temp for last 24hrs were 15.5 min. and 18.0max. I've brought them into my living room and will monitor temp and any changes.
Thanks again for your trouble.
