I'll Give You a Hint: I Added Some Floralicious+ When it was First Mixed

Here are a few more hints:
The plant started in this bucket as an 8" clone and has been kept as a bonsai mum under the far end of a 4' shoplight. (not much light) Lighting schedule is anywhere from 16-24hrs of lighting a day.
Water is reverse osmosis filtered with GH maxibloom, and pH up. Pro-tekt was also used once or twice, along with the single dose of floralicious+.
