Week 4 flowering with CFL's LOTS of PICS

Hello everybody, I'm currently growing two ladies in a grow box that I constructed in my room. The strain is Kushberry, and I am running 16 26w CFL's which equates to 416 watts. The grow room itself is made out of PVC and I used mylar, which i wrapped around the pipe, I also placed a dark tarp over the outside of it. I am running 3 small desk fans inside and I'm using a passive intake and just a couple vents which are near the top. I grew these from clones that I got and i am using general hydro's flora series and currently for the flowering stage Im feeding once every 3 to 4 days at 3/4 strength, and I have not seen that much burn occur. They were rooted in a Soil less mix. Here are a few pics and let me know what you guys think, thanks! Oh before i forget, as flowering progresses is it normal for some of the lower fan leaves to yellow/die off? Btw the last pic was during the veg stage.

Looking nice i got some kushberry going too at 5 weeks,stretched alot i have a strong fan but all three are lanky.next time i will lst

Btw yours are looking hell of alot better than mine and im at 5 weeks

Haha thanks, I think the key to avoiding the stretching is keeping the lights close to your plant. In my case im using the CFL's so they can literally be within 1-2' of the plant, without burning them.

I use 600 hps so its not right on top

look very nice...bushy, green & healthy! and the answer is yes, concerning ur fan leaves.

Looking good, I use to grow with cfls, now im using a 600 watt hps with a few cfls on the bottom for added light. keep up the good work man!

thanks guys, my next step is definitely invest in some HPS/HID lights, and I like the idea of supplementing the light with CFL's along the side of the plants.
