Strawberry Banana Outdoor 1st Grow

Decided to put up a horticultural fleece during week 19 to try and help with the dropping night time temperatures. Seems to have responded well after all the tugging, poking and prodding I did to install it. I took out some of the central fan leaves to try and give it the best light and also swapped over to Biobizz fish mix which seems to be going well. Who knows if it's any better than grow? Decided not to force flower but I'm not sure if I'm starting to see the beginning of some flowers!! Not currently sure if it's new growth... Update after grow question- definitely starting to pre-flower (thank you to everyone that answered). After some reading I reckon I'm (mid way) in the stretch, so maybe a week more of fish mix then I'll be switching back to BioGrow and adding BioBloom and TopMax .
