great start sir, all looking good...have some rep dude
for getting a journal going...I've got the same size tent as your, I can tell you now its going to get crowded with 4 in there, you may find that with those LED's their light penetration my be a bit naff. You may want to scrog with that many plants, that will help loads with light getting to those lower buds. That's what I'm doing, I'm only growing 3 plants, going to scrog 2, and plenty of LST on the 3rd.
My plan after I get these lady's to harvest (it will be my 3rd) is to then stagger my grows of popping a bean every 4 weeks, should leave plenty of room for training in the tent...Have you thought about topping, that's will help with room, I've just done it, pop on in to my journal to have look dude...multi colored link below.
