Hey guys, what does this look like to you? And why has it not affected all of the plants? Any advice would be greatly appreciated. Thanks!
I would put it down to suffocated roots due to over watering/under aerating due the rockwool holding on to too much water. Larger plants suck it dry in good time, but smaller plants can be left behind and sit in wet rockwool for too long
I love the foam inserts used in Aero Gardens... I Start them on the Aero-- Till they have a good long tap root then I go from there
