Wierd spots on chili leaves :(
 

All the leaves on both my chili plants have these spots of brown and discoloration, is this a deficiency, or is it too much of something?

After a bit of research i think I found my problem. I am using Ammonium sulfate in my mix. Apparantly because ammonium is absorbed so rapidly by plants, its creates a toxic situation. :(

thanks for the info, can they recover if you change the nutrient solution?

Not sure, guess well find out :P
