New Grower Wrinkly growth, possible pH issues. Assistance requested.

Hi guys. Some of you may have seen my variety grow in the 'indoor growing' forum. Come say hi if not! I'm a very new grower and I have some odd growth that I'm a little worried about.

As you can see, this White Widow has some pretty curly growth.

All of the seedlings have the curl up characteristic. Not sure if this is normal.

Setup: 4 seedlings inside 7.5l airports in Botanicare CocoGro under a 125 watt CFL, soon a 400w hps. I'm using the General Organics GO box. Following their schedule to the letter using tap water.

I think it's probably from being a newbie and doing things like not watering evenly(still getting it down), letting the temp fluctuate (it got up in the high 80s for a few hours). One thing I did notice is that the medium's pH is @ 7.3, but I took pH of my nutrient solution and it was right at 6.2. Do I need to add some dolomite lime to the coco or is feeding with the proper pH level solution enough?

it might be because you are giving them too much nutes your only supposed to start autos out at about 1/4th of the amount stated on the schedule

Rough Calculation Guide:

Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference

If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.

For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5

If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5

So 1/4 nutes even in soilless? I'm using 100% coco.
