Hey pal,
I'm not the most experienced but I can share what I know and the experts can correct me as needed. I believe you need to raise your humidity a little bit. I think you should be consistently between 50-65%rh in veg. Also, consider buying nutrients for cannabis - its a bit more selectively on the nutrients instead of a one-size-fits-all fertilizers. I'm sure it will work, but to what degree and how much deficiency will it have by only using jobes. The light green color is telling me it wants more food. Be careful on the overwatering as well. For balling on a budget, I would consider the 3 part from General Hydropnics (FloraSeries.)
it's a weed, do the right things and it will heal :)
