First off, tell us about your soil, it looks rather compact, even though there's a bunch of perlite(I think) laying on top. If it was a decent soil, you've fed it too much, but still, I think your problem is bigger than that. Even though overfed, it's not really showing signs of fertburn/overfert, it's showing deficiencies. That's probably a PH problem, and/or you have a bunch of dry spots in your soil, even after your watered. Dry roots can't take in nutes, and if your soil is too compact, or not watered thoroughly, you'll end up with dry spots, which can really screw things up. They'll fool you into overfeeding, when in reality, there's plenty of nutes there, but the plant can't access them. Watering in two doses, can fix that, if done right. Break up the top of the soil, with a chopstick, piece of stiff wire, small screwdriver, etc....and then give the plant about half of it water, wait about 1/2 hour, then give it the rest. Water til there's a little bit of runoff, just to make sure things are good and saturated, evenly.
Also, invest in some PH up and down, you won't regret it.
