Your nutes you got will work fine, generally for vegetative growth your mix has higher ratio of nitrogen (N) than phosphorus(P) or potassium(K) like 15-5-10 or something similar then flowering you want more phosphorous 5-15-10 using the same basic ratio. It will take a few weeks for your plant to start growing properly again since you switched her out of flower, remember when you do flower your space needs to be light proof or it will delay flowering and potentially cause hermies and other problems. When it comes to watering most strains enjoy going from moist soil to dry soil, its pretty hard to underwater your plant but overwatering is ir-reversable, learning the difference with weight of the pot is a good idea until you get a good idea of whats going on. Overall your setup looks pretty good, your gonna want to invest in some more lights down the road for flowering, its well worth the money to get a low wattage hps setup, but more light is always good. Right now just be patient its gonna take sometime to recover, if you replant then go get some good soil, you can order it if you have to, not sure what state your but we have hydroponic stores that have everything you would ever need, fox farm ocean forest is a good nutrient rich soil that would probably last you awhile considering your only running 1 plant, feel free to hit me up, Im fairly new to indoor growing but I'll help all I can, peace
