Yeah I'm having trouble trying to find a good pic to compare but I cant really find one.that looks like a deficiency to me.
iron maybe.
Imma give her a little more food, the other plants don't look like that at all!Your plant is hungry. Feed it some veg nutrients or transplant into a bigger pot with new soil.
Thanks for the info!sounds like you need a little extra nutrients to me.
Looks like phosphorus but i really am no expert its a place to start thoSimiliar situation... this GSC is 4 weeka into flower, an unfoetunate overheating accident damaged her in the beginning of flowering, some nutes brought her back ten-fold... now mu environment is regulated... all othet plants are fine however toger stripes on my main fan leaves... im watching them die slow and I can't tell the deficiency... anyone tell what type of deficiency these leaves reflect?
