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

It really takes alot to light bleach a plant, I believe more than what you are working with. They actually look great to me. A couple yellow spots here or there are nothing to get to worried about. Just keep an eye on them. Hope this helps, Good Growing.
Got a pic so we can see what you're talking about?
@am420 Where they under this light for an extended period of time or are they transitioning to a new spectrum?
This sounds like nutrient burn/deficiency or some other variable than your light intensity if you are reading under 300ppfd. What media/nutes are you using?
