CFL Grow White Widow Fem., Foxfarm soil and nutes.

This is my second official grow. Both have been closet grows and both with CFLs. Currently there is one white widow fem, from nirvana growing under 1 300 w cfl 6500 lumens and 2 100 w cfls 1700 lumens each i think, those are the equiv wattage. The grow area is 3lx3wx4h. The soil base is foxfarm's ocean forest mixed with perlite and vermiculite. Im about 5 weeks in and I started 2 weeks ago with foxfarm's grow big, and now this past week have started with the big bloom also but all at half doses. I also have the tiger bloom but will wait until the 12/12 cycle to start with that. Any advice with these foxfarm nutes would be appreciated. The plant is looking really healthy and is a nice dark green. I have a few questions, Do you think i need more CFL lights before I flower, if so around how many? I plan on adding at least another 300 w and 2 more 100 w for flowering but am wondering if i should just do it now, or if i should need more all together. My thought is that the boost in lights will act as if it was switching to like an mh light or something? Are soft white CFLs ideal for the flowering stage also? Thanks in advance.
Pictures to come soon.

When you flower, the more lights the better. 2700k, aka "soft white" is what you want to use for flowering.

So I have been using foxfarm nutes with incredible results... almost too good. Overnight my plant grew right into my 300w cfl and has crisped up a nice amount of the new growth. Now I'm wondering if I should top it, trim the burnted parts, or just let it ride out. It's only 6-7 weeks into veg but it is getting beastly. I hope to have a camera to get some pics soon. Any advice would be appreciated.

I say let it ride out.

After a few days of little to no growth on the top, it has now started to sprout up again... I think that the bottom was growing more while the top wasn't. Anyway the only down side to the burning is that it has delayed my plans of clipping some branches for cloning, I don't want to over-stress it. Im thinking maybe next week or the week after start the cloning. So now I'm 7-8 weeks into veg and am upping the nutes to 3 tspns of grow big and 3 tspns big bloom per 1/2 gallon water. The plant is a rich dark green, looking really healthy, other than the few yellow streaks from where in got burnt. I'm going to have to move it into a bigger box soon because I definitely underestimated the size of her. It is probably about a foot and a half now and growing quick. Im thinking a portable closet or something. When it moves to the new box I will add some more lights as well. I hope to have pictures by my next post.
