Consistent yellowing and curling up of tomato leaves
Iv posted before on this topic but here i am again. Apologies. Judt hoping to get a better understanding of what the problem is here. The leaves have getting yellow blotches and curling up. After a few days the yellow blotches turn to brown patches on the underside of the leave.
The only thing is seems to be is maybe leaf mould from poor ventilation. Can anything be done about this other than increasing the ventilation ? Can i spray any sort of fungicide ?
I have cut off a few of the bottom leaves aswell to try anf increase vemtilation and circulation.
Please and thanks just want to know whats causing this!
