such light are good enough for seedling and early veg but far from being powerfull enough for veg a larger plant or flowering.
you'll need a much more powerfull light for flowering to achieve good results.
for exemple have a look at:
(seen from your amazon link that you seem to be in uk other way there's also some .eu or . com portal or more depending your locations to avoid extra custom cost)
(some menu link to the various lights series seem broken on the
spiderfarmer uk portal so here the direct links to each series)
for the SF series, smaller models should be enough for one plant
Spider Farmer SE series, led bar design with Samsung LM301B diodes. High efficacy up to 2.9umol/J. Uniform PPFD distribution and good heat dissipation. Dimming daisy chain, easy to control, perfect for vertical growing.
another brand for you to compare, i would just avoid the TS series with that brand and would opt the the FC series with samsung or bridgelux LED models

So I've place it at a window that's SE facing. It's been getting direct sunlight from sun up (currently around 5am when it's high enough, until around 1pm.
From 1pm the sun starts heading over the house so it's them getting indirect sunlight.
same light from the window only while enough for veg might not be enough for flowering if you want to achieve dense and compact buds.
I've just up potted it today (really hoping it's going to be ok from the move)
you could have used a bigger pot that one is still rather small to sustain lot of bud growth. But that could do the job for a not too big plant, smaller pot just require more micro-managing with feeding and watering and won't sustain lot of bud growth with soil.
Most people will work with 6L to 15L pots with a vigorous auto and depending the set up.
