Royal Dwarf - My first time growing!

Here is my diary for my first grow ever! I’ve chosen 3 x Royal Dwarf seeds to start with as I have heard they are relatively easy for a first time grower and give decent results. All 3 have germinated successfully and have been nicknamed accordingly, 1 far left is “Tinkerbell”, middle is “Verne” and right is “Lazy”. Lazy was close to being binned, during germination her roots were very short and very fat under the soil, unlike the others whose roots had dug deep down the soil by that point - however I gave her a chance, and thank god i did as she corrected herself overnight and is now looking more healthy. I am using coco soil and a 200W CFL light with reflector on a 20/4 schedule, this is a low budget grow hence the use of the CFL light. It’s also my first ever grow so any advice or tips are kindly accepted 🙏🏻 I am using a small amount of nutes during my grow and will be flushing a few weeks before harvest if all goes well
