Thankyou for the useful information! Will deffo give this a go if the dome I created doesn’t work lol. Thanks again

Shinsimilla how would you create more humidity? They are too big to fit into the dome in these pots

Nope, it's the environment. The roots are not developed enough to survive in normal conditions, they need more humidity. If you don't fix it soon, they are going to die.

Some of the fan leaves have literally just crumbled off so now only left with the top ones,I think the ones that were crispy weren’t doing the plant any good any way, hopefully will see improvement over next couple of days would you just keep spraying the inside of the box?

That looks much better. Keep it like that until they perk up. When their leaves start to look more happy, slowly lower the humidity day by day. You can just raise the box more and more so more air comes in. I would leave the temperature where it is for now. Warm and humid is mold heaven, you could even go down to 20C to be safer and it's more than warm enough for your plants to be happy. You are not trying to make them grow right now, just recover.

Temperature and humidity are looking good now! Once they get a bit bigger and stabilize, you will want to get the humidity down another 5%-10%, but that's not for a couple weeks. Keep on keeping on. Good luck!
