I am a n00b in all this, but inspired by Rusty CFL talk I am building a clone + mother mini-grow only with CFL lights. Let's see how it goes... :rasta:
But I confess LED seems very promissing!

About my girls, I can tell the problem is gone now. All the new leaves are growing without burns but the old ones didn't recover.
It is still a mistery what happened and I don't now if I actually fixed (and how) or if the problem went away.

The only two things that I did was:
1- Stopped using mineral water (changed to tap with 48h rest)
2- Start balancing the solutions to PH 6.0, instead of 6.5/7.0 like before.

One thing about my soil mix that I think you guys maybe missed is that I'm using 50% of perlite with it. Doesn't this make it work more like hydro? Without nutrients? Maybe thats why the slight lower PH worked better?

Thanks again guys! :smokin:
AnomanderRake Reviewed by AnomanderRake on . Fert burn or K deficiency? Hello growers! :) This is my first post here in this great forum. I've been reading a lot and started my first grow, and until now I had no problems. Last week two of my plants started to develop burn tips on some of my lower leaves. It quickly spread to most of the leaves, some with more intensity and others with less. I read a lot and saw loads of pictures of problems and deficiencies, but could not deicide if this is a Nute Burn or some kind of deficiency (Potassium?). It's hard Rating: 5
