Very first grow.

My diary is a little late to the party as I just found this site. These are a White Widow cross that a friend gifted to me so I dont really know exactly what they are. Its my first time growing but with some advice and research I feel I'm doing ok. I wasn't comfortable topping so I just pruned some leaves and lower growth tips that won't get light. I'm not sure how old it really is so I'm just guessing here. Feel free to point out anything that needs work.
