bonsai troubles

hows it goin , i gt a problem with a bonsai mum any help would b appreiciated,ne ways , shes about 1 month and a half under 3 CFL`s , two 42watt 2700k and one 45watt 5500 coolwhite 24/7. i dont have ph gauge and i have been watering with bottled water is that good/bad for it at all? also i juice it up about once a week of the shit below ,which is just 20-20-20 , also i have a small fan mounted on the wall with noht the bst but decent airflow, so the problem is the yellowing at the bottom, i give her nutes about once a week why is she doin that ? should i remove? is it time for more light?, thanks ne help would b awsome!!

how big is the pot shes in? it could be root bound, the stem looks big, but i cant really tell. remember that the roots need to be growing as well as the plant above the soil, and we all need room to grow. beyond that idk, when i grow i use flora gro (for veg) and flora bloom (for flwr) and the plants seem to like it. beyond that im not sure... good luck sortin out ur problems man, and if u do decide to transplant, be careful of the roots, they are fragile
