We planted 3 different types of tomato plants in a growbag specially set up for tomato planting. Only one is producing fruit the other two - Moneymaker and F1 Golden Sweet have produced plenty of leaves, sideshoots etc but not one hint of a flower bud. The plant leaves on both have started to curl in on themselves and both feel and sound quite dry. So in short one growbag three different types one growing well the other two seem to be dying off?????
