hey guys I've noticed today the new growth at the top of my plants are very wilted. I'm running a RDWC with 9 totes(2 plants per tote) all the other plants seem to be ok except this one. I'm running canna nutes(a+b) at 450ppm. Ph 5.8-6.1 Air temp(68-75) Water temp(68-72) Rh (50-60) Roots are nice and white with 2 air stones in each tote. Any help why my plant would be doing this would be greatly appreciated. Cheers
Ppm was 650 but have dropped to 450 hopefully my baby will make a come back. Only seems to be wilted at the top of the plant
