RQS Northern Light | First Grow

Thu. I added the 300W CFL (Not LED) only to find out half of it wouldn't ignite and proceeded to blow! Replacement on the way! In the mean time I added a supplemental 60w CFL also helps get better photos coincidently! This week saw an explosion of growth keeping up with the doubling size and leaf matter on a two day basis! She's started to grow branches out of the nodes yet she's so short it makes her extremely bushy, I was expecting a tad more height maybe 2cm between the nodes not 1? Not sure if I'm under feeding or over feeding, probably neither but seeing this is the first time I've used fertilisers while also being my first cannabis grow I'm always questioning myself if anything is off. Fri. This is the last week of Root•Juice (until I attempt to sprout the topped section) so I'm being a little more generous with it (1ml - 2ml) since she's doubled in size I am hoping she will use it well! She seems to refuse to grow taller but instead out and bushy like, I assume that's my fault with having the lights so close? At 11" away it wasn't heating up the pot too much while also giving a nice reading on the cheap lux metre (reading taken with a grain of salt) and it was also close enough to the plant where it wasnt too cold nor too warm to my palm. Sun. So the week ended off well and a little more favourably for my plans with her gaining height, I know her genetics make her shorter but kinda expected a little more so I probably stunted it a little with having the lights at 11" away.
