Opie,
I am equally confused and actually rather upset.
(we've been thu this b4, u'll rememmber)

i used at approx 60% strength.

the CFLs were within 2-3 inches as usual.
they are not hot.

I am convinced it must have to do with the light spectrum and "quality" of spectrum produced via CFL.

Why am i convinced? because all of u using it in veg are using MH or some other hi output lamps without these issues occurring.
Also, when I use it in flower (HPS) i do NOT have these reactions.

the leaves got bleached some, kinda discolored and the tips curled/shrivled.
it happened to the soil and hydro's i had in veg locker,

matter of fact, it affected the hydro plants so much, that i will be chopping both down to clone out and hopefully save the strains by cloning out.

until u show me one other grower using LL with CFL's without problems, i remain convinced its CFL related.

its ok, i just know for sure i will only use LL in the 1st 4 wks of flower.
thats actually ok with me, and now i know the limitations of LL for my applications.

just wanted to share real experience data.
