Strawberry Banana Outdoor 1st Grow

Decided to try some BioBizz nutrients so I've been applying them for the last 2 weeks starting off with low-med strength to see how things go. Seems to have worked wonders!! Not sure if it's the new feed or the heatwave we've just had but I have a feeling it's mainly the feed so fingers crossed it keeps giving... I've been debating doing some defoliation to get rid of some of the big fan leaves blocking some light, but I keep reading they do all the magic in terms of light input so still not sure... Also a little concerned I havent started flowering yet as it's getting colder at night. Considering beginning force floweing in the next week.
