Give some more info. How old are your plants? When did you start giving them nutes? Where are the brown spots?? (PICS?) What kind of nutes are you using? Check out the FAQs and do some searches. Cheers.

In the meantime, flush them with regular plain water that is pH correct. And then back off on the nutes. 50% or so depending how bad they are.
