Leaves curling upwards?

[MM2K6]

I've always worked on the general rule of thumb that leaves curling upwards has an environmental cause, heat stress or humidity issues etc, and downward curling leaves mean a problem with your rootzone.

could be root zone was packed with roots before transplant and root were pretty dryish..

Sounds like it, water more frequently with Coco, but again this will be controversial among other members

will up the water timer to go for a few extra minutes. I water 2 x per 24 hours @ 5 plants around 20 liters per 2 days if that helps?

I'd add a watering rather than make them longer , you will still have the same amount t of drying time between watering, the coco won't hold much more water than what you give it it will just run off and dry out the same speed, smaller more frequently is the go but that's what works for me
