is my 2 month old plant a dwarf?

Ok so I have a 2 and a half month old plant and well its very little lol can anyone tell me what im.doing wrong fyi its my first time growin and I have it growing on my window sill I have schultz 10•15•10 that I feed it twice a week.

Without a picture I can definitely say that it's a mutant dwarf.

With that fine sharp picture and the detailed description of all the details of the grow, including strain, container size and actual plant height it's obvious. I would say it definitely needs some more, then cut back a bit in 11 days.

1. Not enough light.

2. Too much fertilizer

3. Throw out the Shultz fertilizer......it's not a good choice for marijuana

4. Buy a good marijuana grow book and start over.

root bound?

Move it to a different sill,maybe not enough light is it facing west? Where are you located? I mean exactly and I need your social security number as well to help any further than the fore mentioned remedy
