looks like you tried to do a sea of green method, and let them veg WAY too long. Before you put them into flower I suggest bending them completely in half, and then when the tips grow back towards the lights, bend 'em over again, and then let them work their way towards the lights....you're going to have one hell of a shrub. And yeah - i'd suggest putting that 1000 watt up too...with that many plants, you'll need it. You also should enclose the area you're growin in so you can maximize your lumen output to keep the plants dense with tight nugs instead of feathery airy crap....good luck
