The spots showed up three days ago on one fan leaf and today 3 or 4 fan leafs have been hit and are about dead. Temps are good. Light could be a lil close. Im only watering every three days. Using only 1/2 strength nutes. Havent checked ph because last grow went off smoothly. thanks.


 
This looks like Manganese toxicity. Check soil PH. If it is too low, it will increase manganese availability and cause problems like you have.

Flush before you do anything. It can also be bult up nutes in the soil. If you don not flush and try to correct then you can end up doing more damage. A flush to start is always a good idea. When watering always remember to allow for about 10% run off to avoid letting nutes get built up. If a flush doesn't help then start going after other options at least you know you are starting off on a good foot so to speak.

Oh and make sure you ph. That can cause huge issues.
