At the beginning of July my neighbours kindly gave me 5 tomato plants 'Golden Sunrise'. I potted them up in 9" pots with compost from a grow bag and put them in the greenhouse. The new leaf growth is tightly curled. I have done some research and think I may have caused this to happen, as I fed the plants with tomorite before they needed it. I also think I have also over watered them, indicated by the lower leaves curling inwards slightly. Please could I ask for some guidance on growing tomatoes in a greenhouse before I kill them by ignorance and kindness. When do I feed them & how often? Thanks in advance.
