Thank you so much everyone. Not an unreasonable question to ask re. whether I'm sure I'm removing side shoots and not trusses - I did get a shock a few days ago when one source stated that trusses can indeed come in the elbows. I don't know how true this is, given that every other source and video shows/states it's the ones in the elbows of main and side stems, but it certainly gave me a fright. Anyhow, all the side shoots I've removed have been leafy, and trusses don't have leaves (apparently), so I think I'm safe. I have not removed anything from the main stem directly. And yes, my balcony is behind another block, 3.5 hours is the best I can get, seeing as allotment waiting lists are 4-6 years on average. Oh and regarding hardening off - I did not do this. Could that be a problem? And lastly, does anyone know how many weeks from planting out it usually takes for trusses to begin to form from the main stem? I'm on week 3 since transplant now, some sources state 4-6 weeks - so is there still hope? If not, I will make a tomato leaf pesto recipe I found. Because there are MASSES of leaves, haha. Oh dear, well nevermind. Other veg seems so happy, so I'm happy too.
