One of my rooms (16 plants) has one Lemonberry (8 weeks flower) that overnight turned brown and looks to be dying. I chopped it pulled it out and saved what I could from it. I looked carefully at the neighboring plants and see no signs of trouble - all look healthy, leaves look good top and bottom. Should I take any precautions with the others or just chalk this one up to a sick individual? I run a soil mix in 3 gallon softpots so nothing is shared between plants except the air
When that happens to me I almost always find underdeveloped roots. One plant won't be quite as green or vibrant from about week 3 or 4 on and towards the end will just give up and fade.
