It actually gets easier as the week goes on, as the number of US-centric questions goes down…

Thank you also for the very detailed reply - from those options I think 1) and 2) are unlikely in my case - it’s a pre-fertilised compost designed for cannabis and should still have enough nutrients (plus during various stages of panicking I added N-Rich fertiliser (Fish mix) and no change occurred). This leaves 3, which has been the suggestion of others as well - although from your explanation I’ll be careful about reusing compost and will use new compost and add further fertiliser if required.

Thank you - yes, I’ve really struggled here - despite the pot feeling light and the top layer being dry, it turned out the lower levels were soaking. I’ve been (annoyingly, according to my wife :-) ) very careful to move the plants out of shade though, so hopefully that part isn’t a problem.

Great, thank you! Just have to hope I can rescue them before the “auto” part kicks in - it would be a shame to have to start again.

Thanks - more compost has now been ordered :-)

Deep rooters! I’ve just done some repotting before reading your reply, actually downsized slightly and added a lot of drainage as the roots were basically nonexistent and I’m trying to force myself to not overwater now. When the colour returns and the repotting stress has passed I’ll follow your advice and go directly to the “final” pot size.

Thank you again :-) I have been watering when the pot is light, and the top cm or so is dry, not letting it sit in water but watering enough that the water runs through. I’ve spare compost and perlite, so I’ll try quickly repotting, in case the soil’s now too compressed/waterlogged, then follow your suggestion re the watering frequency and try and forget about the plant a little!

Nochmals vielen Dank! Thank you again - I’ve got compost left and some extra perlite so I’ll mix some more in and repot now.

Thank you for the detailed reply - I’ve previously had no problems with “normal” plants but it really does sound like I’m killing these with love. Very, very jealous of your beast!

Thank you! I’ve hopefully added a picture. I suspect that you’re right - every time I mention the plants my wife rolls her eyes….

I’m leaving the flower pot until it feels light, then watering well, and the water drains freely. The top layer of soil currently feels “sticky” after being watered a day ago - I also check that the top 1-2 cm is dry before watering. I’ll resist any further fertilisation unless the photo makes people think there’s a nutrient problem.
