After a very successful first grow I have had the same problems with my last two grows. The leave as you can see in the pics are yellowing and turning brown on the edges. I can't figure out why this is. The seedlings are Nirvana PPP and about two weeks old from germination and only about two inches tall. The soil is FF light warrier with one application of FF big bloom at half strentgh and lighting is two ea. 100w cfl's.
Water is rodi.
Any ideas as to what I am doing wrong?
Thanks
