Micro-Grow flowering! (Light distance from plant! Slight Discolouration) "DWC Help"

THIS WAS SUPPOSE TO BE POSTED 01-21-2012
BUT DID NOT SEEM TO WORK!

Hey guys,baby girl is about 4 or 5 weeks into flower,Cant help noticing the yellowing and drying up of some fan leaves and slight discoloration!
flushed my res about 4 days ago!
ph is around 5.5 - 5-7!!

the temp is around 28oC when all lights are on!
thinking of a bigger box! but not too sure atm as she is past halfway!!
should there be more orange warms in there?
there also does not seem to be much bud growth underneath or down the side!
how rapidly does it flower?
will i need a bigger box,will the cfls damage my plant?

thanks helps much appreciated!
peace

here are some pics,what do you guys think?

I would look at Potassium. I'm pretty sure it can only be taken up by the plant if the ph is 6.0 or higher. Would like to hear some others myself.

That is, if that is soil your using. Can't tell.

Ok. Just saw that you listed as DWC. So not sure as I only grow soil. I still think potassium lockup or deficiency though.

well for one its too hot in there. You can see it in the picture of the leaf tip curl upwards .

Either your ph is off and causing a nutrient lock out or your just using too much of one or more nutrients, pretty much as simple as that.

That kind of makes sense,Been having exhaust issues since forever!
I have added a mini homemade AC unit, which doesnt seem to be working the magic I was expecting!
havnt had it running for long today! as it was lights out soon after installed!
got it down to about 26 - 27oC with no added warm lights! "as i said it was not running for long as it was lights out" *might of had an effect*

Also there is not much room left for her to grow! Was wondering if the size climate will effect her growth?
been tying her down as a little! but box seems to be a little small!
but i seen it is possible! in a PC!
So yer!!
Thanks! you guys here are way better help the on Grasscity lol!
appreciate it heaps!
cheers

Quick photo update!
