    the edges of my plants leaves are getting a bit yellow, some have browned and died. the leaves have also begun to dry up a bit.

    are they being burnt?
    is it possible that they arent getting enough water?
    is it bad to have your box above 80degrees F?

    thanks

    If the plants are dry the TDS in the root zone is high. Adding water will dilute the TDS in the root zone. If you are using full strength nutes u may only be able to use nutes one watering per week. The rest should be plain water. If u use half strength nutes then every other watering should be plain water. U also have to take into consideration that the nutes will build up after a few feedings and they either need to be flushed out or u can lower your TDS for a week every 2 or 3 weeks...
