Critical Orange Punch Microgrow

About the environment: This plant lives in a desk drawer with the dimensions of 30*30cm. For vegetation I use LED bulbs: 1x 4500K 17W 1x 6500K 13W 1x 3000K 13W These bulbs are not designed for plant growth, but they still do the job. Once she enters blooming, I'll switch 6500K with another 3000K. Day 1: Started her in 500ml cup, will transplant to a bigger pot in about two weeks. Since I'm using coco coir as the growing medium, I started feeding right away. Added 0.2g of GHF Grow and 0.5 of TA Cal-Mag to 200 ml distilled water and fed her with 10ml of the solution. Day 3: It became a tradition for lights to get fucked up during seedling stage. One of the bulbs blew up, LITERALLY BLEW UP. She stretched a lot due to light lack but I'm trying my best to keep her healthy. I fed her again, with 1/2 cup of the nutrient solution: In 1 Litre distilled water, 1 gram GHF Grow and 2 ml TA CalMag. Day 5: Added another bulb and fed her one more time.
