Lower Leaves are drying and dying on all cherry tomato plants
The lower leaves of all of my new cherry tomato plants look like they are drying and dying. Not sure what it might be, perhaps hot temperature, now the temperature is 74F although it was around 86F for some time, because i thought that was the problem. Can it be the problem? I use 24hour CFL lights, I'm growing hydroponically with Soi.l Its my first time though.
