CFL - DWC - 3 weeks from clone. yellow/burned leaves

Hey RIU community. My 3 week old baby is showing stress signs and I don't know what to do. Unfortunately no pictures!!! I'm on a tight budget also, thus I don't have a pH meter... I think this is my biggest problem.


150 watts bright white CFL's
10 gal rubbermaid
2 airstones
3 weeks old bagseed from clone.

She was growing fine for two weeks, then I topped her. Since then, her fan leaves have been dying off from bottom up. The new head growth is also more yellow then green, while the stems are red and purple. Ideas? any help +rep thanks

now there turning crispy and brown and completely dying off. I changed rez... don't know what else to do. I have some pH up and down just no tester still hah
