    Keep getting light burn? Help me

    in Grow Community

    Hey guys I was hoping I could get some advice here ..... im growing 4 plants in 5 gallon fabric pots..they were cutting given to me 2 weeks after being cut from the mother. I'm using a spider farmer 4000 led light . I also have an apogee par meter. I'm in week 4 of veg and my lights 30 inches from the canopy and for some reason anytime I put the light past 300 ppfd and leaves will start to curl up and the color gets bleached a little.

    My day temps in tent are around 80 in the day and I'm even running my co2 already . Shouldn't my ppfd much higher by now I was gonna flip in about 4 days..Can anyone please help me?


    Thank
