This is my first time in rockwool after several successful runs in a soiless medium. I am using 40" slabs hung vertically with 4 girls per slab. all my climate conditions are right, constant 76F, 55%rh, 1500ppm co2 ect. the only thing new to this grow is the medium which leaves me wondering what my watering schedule should be for clones transplanted 2 days ago. to make things a little more interesting the clones where taken in jiffys and not rockwool cubes so they hold moisture well the rockwool dries out much faster. I started watering every 3 hours while the lights where on for a total of 6 times and notice some leafs curling, I took it down to ever 4 hours with little change over the next day, I will now try every 6 hours to see what happens.
Can anyone let me know their watering cycle with rockwool slabs or even cubes.
I've included a pic so the post isn't useless, you can see the new growth curling sideways but i really don't think it is a heat stress issue from lights too close because i am familiar with that and this seems different.
