    Default Possible PH problem, or other?

    These super lemon haze seedlings were planted 7 days ago. 24/0 under HPS in soil, they've been watered twice when the top inch was bone dry, no nutes yet

    This plant started to show a yellow/brown patch on tip of one if it's leaves yesterday:

    Today this plant shows some of the same discoloring:

    I have concerns about this plant being very yellow and tiny compared to the rest:

    For comparison this is my largest, most healthy looking plant:

    I have 7 plants overall, all from the same pack of seeds under the same light in the same medium. 4 look very healthy and happy and it's these 3 that are being difficult

    Thank you, im growing in soil and to be exact it's called "Plant Magic Plus - Soil Supreme". Got recommended this 1 although I did wonder if i should have started off in a lighter soil and repotted in to this later

    Thats good compost however it could be slightly over fertilised for seeding...Try flushing a couple of litres of water through the pots it should help leach out some of the nutes...Also they could be sensitive to the light intensity at such a young age, raise the light 24 to 30 inches..

    Thank you for the advice. I will try both of these things and keep an eye for any changes

    They will probably go droopy and sulk a little after the soaking but should bounce back once they start to dry out..
