I have a couple issues going on with my girls. I had to leave on a trip for 5 days and did what I could for them before I left. They seemed to due fine on water (a little dry when I came back but nothing major), however they do have a few issues other than being thirsty.

First, I raised the lights hoping they would be ok until I got back. They decided to instead stretch (alot) and one grew right into the light burning the top coala. They were nice and bushy before I left. I raised the lights 6-7 inches above the plants before leaving hoping to leave room for the stretch but I guess I didn't leave enough. They are in their 3rd week of flowering so the burn hopefully wont stress her into something awful. Question here is, will new growth just stop on top and transfer to the sides or have I ruined her?

My other question is the canoeing leaves. I am assuming a ph issue. Any ideas on how to correct this? I am using Fox Farm nutes tiger, grow and big (per FF schedule) and adjust ph before watering the plants. I adjust after I add the tiger bloom as it brings the ph way down on me. I put in at around 6.8-7 but cannot check ph runoff because the water comes out colored from the soil and throws off the ph color chart. Any ideas on fixing ph without knowing runoff? I am guessing it is low in the soil, but not sure. They are also losing leaves on the bottom (attached pics) which I thought was ok as they don't get as much light, but it could all be related to something else.

Sorry for long post and thank you for any info. Here is the trouble shooting form from what I can remember without going and getting it.

Indoor
CFLs (mostly red, little blue spec. enough lumens per sf)
Soil (peat moss based soil (80% of soil) and blacks gold (20% of soil) mixed with with lots of perlite (30% of total mixture)
3rd week of flower, 12/12
3 gallon pots (hoping not root bound. plant is 2.5-3 feet tall so I was hoping this would do. they were put into 3 gallon right before flower)
Temps range from 82-84F (day) and make their way down to 75F (night)
Tap Water (open 24 hours to lose chlorine, adjusted ph roughly 6.8)
Fox Farm nutes (tiger bloom, grow big, big bloom) (Per FF Sched., every other watering, roughly once per week) (also using unsulf. molasses on no nute day)
