thanks heaps regards ree0004
By "RM past 30%" do you mean relative humidity? And by "sumps in the bottom" do you mean water pumps (looks like you've got an eletrical cord going into the res)? Are you using the pumps to feed water to the roots, AKA Bubbleponics?
Regardless, from the pictures it looks like you're having pH and/or water temp problems to me. What is the pH and water temp?
Do you chase the pH...by this I mean try to keep the ph at a certain level by using a lot of pH up/down? Rapidly fluxuating pH or pH out of range can cause the problem you are experiencing.
If the water temp is high (above 75* F) and the roots are in the water and the pump is used to feed water to the roots then I would turn off the pump and see if that lowers the water temp.
BTW, nice job with the LST!
