It kinda looks like your soil is too hot. What does your soil mix have in it and how much (should have it on the bag)?

Also gnats are real bad. Most people dont take them seriously but they spread disease and they eat your roots when there is nothing to eat or the soil gets to dry. They like moisture, and u should take that into consideration because its usually to wet of a medium that attracts them.

I would have to agree that there's a problem with phosphorous, but the plants look underfed despite showing some clawing. They're also a rather light green, suggesting that more nitrogen is needed.

Not at all familiar with the feed you're using, but I'd have to say it's weak for what they want off-hand. Also, if you're growing indoors, IMO you need a pH meter or some way to be sure that you're giving the plants feed at a pH level that allows them to utilize what they're being given. In other words, get a meter, know your pH.
