Slightly overfed, and slight pH issues. Lookin' good though man, reminds me of when I was just starting out!!
A few quick words of advice:
Look into HID lighting, even if it is a 150 watt HPS for flowering. Puts off very little heat, but will get you much better results for around the same electricity.
I'm not sure what soil you are using, but if you can't afford pH tests, it is usually better to go with a soil like Happy Frog that is sort of discreetly tailored towards more acid-loving plants. Most potting soils you find are treated with lime, and therefor have a pH ~7.0, which is FAR too high for Phosphorous to be properly absorbed. This leads to poor root development, and poor nutrient metabolism. (A Phosphorous deficiency can actually show signs similar to nute burn, considering Phosphorous and Calcium are used in nearly every metabolic process the plant undertakes regarding nutrients.
I will say this though...Keep it up man!! A few tweaks here and there, and you will have it. I'm not sure what genetics those are, but I would also recommend looking into TGA, you will be taken care of. That kind of looks like some bagseed type of sativa, honestly. Can't ever tell too much from a pic though.
+Rep, and keep it going man!!
