Any ideas what's causing these leaves to curl yellow and die

[Mgvcrowley]

My plant is about 6 weeks old now and since I started to trace this problem I have:
Changed the water in the res
Replaced the lights with cfls 2 inches away
Boosted the nutes same as to the chart
Ph is 5.7
Res is cooled
Room temp 20c
Roots are small but looking good
Res is 15 gallons

I have included pictures has any one have this problem or know what's going on

You replaced the lights with cfls that are 2 inches away.
What light was used prior to changing to cfl?
How many days ago was the change made?
How far was the old light from the canopy?

They were incondesant light and they were far from the plants that's why it stretched and ppm I still need to buy a text kit

I don't know anything about Remo nutes but the instruction looks like a lot of mls per gallon. Like most nutes it's probably best to try half strength. They are green on top which is a good sign they are trying to bounce back.

More air in the Rez The bottom of your Netti pot should be half inch from surface of rez The more bubbles you can get popping the better. Good luck
