    HELP! Seedlings first leaves are yellowing on all three plants

    Any help would be greatly appreciated. I'm a new grower, this is number 2. I'm using coco perlite mix in an octopot, have three plants going at once, Ph is 6 going in measured 6.5 at the res, using seedling strength 1/5th strength general hydro trio, with calimagic per nebula's recipe. Humidity is 45-55 in the room. First picture had a dome on it for a while. All three are showing similar signs. Two are under max sun PB2000 at about 30 inches. They were sprouted in rapid rooter and transplanted into octopots about a week ago.

    Anyone have any ideas?

    Photo or auto flower ? I don't know your light what's the actual draw from the wall? Could be splash of something on the leaves burned them with the light is it too close? I can only say that the leaf looks cooked how old are they?

      The seedlings are about two weeks old at this point. The lights are 600w LED at about 30 inches. Could it be nutrient burn? I was using the coco schedule that I found on GWE. They are Photo Super Skunk Kush. from Garden of Green.

        PH range in coco is 5,5-6,5 so you are in the higher side of the Ph range. Try to lower the Ph down a little bit.
        and maybe try a lower ratio of NPK - they look a little nute burned to me also
        Just because people are over 50 doesn’t mean they know everything.
        You can teach a old dog new tricks - But it will still think the old ways are the “best” lol

          Yes i'd back off the feed and raise the light for now until they recover just water should see green up. Good luck keep us posted.
