    if you cant grow with the nextlight mega ,LED may not be for you.

    its a quality light of high efficiency

    did you use a lightmeter?
    did you raise temps comapred to your MH?

    how much MH wattage were you replacing with the mega?

    Lower the megas significantly to the canopy......5ft away is too far,18 - 24 inches ? Would be my guess, never used one though. Plenty of Samsung mid power grows in here for reference

    Soil heavily aerated(perlite, etc)?proper watering habits? ....... slow draining / overwatered medium with leds is a recipe for disaster

    Could have just shocked the shit out of them if they were used to MH light and switched suddenly to LED. I wouldn't waste your time buying any other LED's because your problems will persist until you figure out what you're doing wrong.

    Get us some pics of the whole setup... This is more than likely user error, and that's ok, lets get you on track so you can be happy with your tools.

    When I hear the plants are all yellow I think you bleached them, in this particular case.

    For most f the pcb led boards 18" - 24" is the recommended space between plants and lights, as the leds are more powerful than folks realize. At full power and 12" that would deliver very high lumen output to your plants causing yellowing. I would try again with light set at 24" and work from that height either up or down. Lower heat levels, but higher lumen levels. From what i have seen of this light you should be happier. @OLD MOTHER SATIVA Sativa has a thread using s similar setup as yours. You might check out his threads.

    Get temps up to 82+. If using a carbon filter and fan combo might I suggest the Mercury 4 fan speed controller. Put those megas at 24"-30" for veg. Sometimes the lack of radiant heat can be a bad thing. Getting plant transportation up to match the photosynthesis rate can make a big difference.

    What size pots, what soil, and what size are the plants now?

    How about cal/mag deficiency ? Have to up especially under LED.

    Agreed - I've noticed the same thing with my cheap Roleadro light in my veg cabinet. When temps were warmer, she was growing fast and eating up the light at 6-8 inches away. Then we had a cold spell and temps dropped about ten degrees. Suddenly "light burn" started to show and I had to raise the light a few inches higher. Bring the ambient up a few more degrees and many of those "light burn" symptoms will disappear.
