no flowers

hi
problem i have is my shirley f1's tom plants are about 2foot high loads of leaves,like a jungle in my green house but no flowers. the flower pods are on top but been like that for over a week now and still not opened.i am thinking of pulling them from the grow bags (2 per growmore bags) and buying plants to replace them with duno if any one else has had this problem before.

Hoot, you need a bit of patience. So the flower buds have been sitting there for a week. OMG - a week ! Tomato flowers can be slow to open, give them time and a chance. They will do everything in their own time. Be patient and see.

 

havent fed them yet,other peoples toms are in flower and also have little toms on theyer plants.my tumbling toms went in later and flowering so i was getting danted. i thought it might be the mirracle grow bags i had used this year that was giving to much chemicals or something but i will try to have more patiance
