Thank you for clarifying that bit as well. The last area to probe is me adding bottles of iced water to reduce the temps. The exposed roots come directly in contact with the bottle, any chances of that playing the fowl?

Do the ice bottles modify the pH in any way?

Do all of your plants get this ice bottle treatment? If so, do the ice bottles change pH in their reservoirs?

Hmm... Not sure to be honest, I grow reservoirs in the winter so I only need a £10 fish tank heater to keep it on point.
During the summer I grow coco so I don't need to lower the temps of the res.

Makes sense, I read up on it, seems very doubtful to be a cause. Thanks for the chart and plan though.

Here's another very useful chart but its something you need to read yourself, I don't explain it very well but go hit Google image search for "VPD scale cannabis."
It's about how rh/temps, roots and plant are all just parts of one continues flow of pressure.
A suck and pull mechanism if you will ...
(see what I mean, what the fuck is that?
A plug plunger ?)
So yeah mate. Go hit Google for that, it's pretty easy to follow. Spend half an hour and hit me back if there's anything you don't understand.
I can explain specific questions on it easy enough but its a bit of a big area for typing lol.
