I am growing lettuce for the first time and started several from a mixed seed package. I'm not 100% sure but I believe this is some type of bibb variety. I am planning on harvesting soon and I noticed some red/brown discoloration to the leaf tips. Is this normal or does it indicate the lettuce is diseased or spoiled?
(yes it's indoor hydroponics but I figured I'd get more help on this thread - I don't think it's anything with my hydro set up because all the other plants are doing well)
