Mega- You should be seal those light leaks up especially when ya flower or it will either still keep vegging or turn hermie, Make your exhaust on the top of you box, your intake is fine down low perfect! Now lights I would go to Home Depot and get vanity lights they hold from 3-8 bulbs whatever fixure ya want but get a couple fixures, only need one extention cord for it so this way you will have say 3 bulbs working off 1 cord. Get cool and the warm for veg. if you still using flo's through flower get more of the red spectrum fluoros these are warm and soft white kind. Iam using 450 watts of light currently in a 1 and a half foot tall Rubbermaid container, I had LST'd all plants so my plants height at 4 weeks budding is 6 - 7 inches tall made it through the stretch period (1st 2-3 weeks of flower plants double there size) lots of tieing branches down from the flourescent lights, and have numerous tops even the main cola if there cause I did not top, 1 plant has 23 buds at the top and the canopy with 3 females is all even , this is what you want with flourescents is a even canopy because flo's lights dont penetrate deep light HID's remember this!You can get the flo's close but if they touch the bulb they will burn, but plant will live just the burn area wont recover. Have you even read a grow book yet? READ AND READ you never can learn enough, I am always reading knoledge is great, Good Luck Mega and keep us informed I'll be checking this thread to help since Iam 4 weeks flower with no problems I should be able to get you some advice and help when needed if of course I can. Get a ph pen, this grow I have is the best yet ( Have done 4 grows ) and I owe it to the ph pen I never check my water/nutrients ph and plants suffered in the yield and in looks with the leave burned and crispy, now all green and lush well maybe not now cause in the bottom part lower leaves they are yellowing because iam not using a veg. fert anymore and Mega this will be normal when you get this far as well.
