🌱 How much have you been watering them? They look a little overwatered. I think they also need more light because they're so tall. 🌱

Seconded.

I water them just before the soil dries out. I'll see how it goes, I'll keep a close eye on them 😎
Thanks for your reply.

You don't want to anticipate the soil drying, you want it to actually be dry--down at least an inch or so. And I would even let it go a drier in your case, until things start to normalize.

Also, it might only be the perspective from the photo but it looks like it's outgrown that pot, too.

No, those ladies are definitely going to need more space before they get rootbound.

What wattage grow lights do you have?
