Northern light seedlings turning yellow

I have 5 auto's from nirvana they are about 17 days old and there leaves have turned yellow for some reason i havent fed them any nutes
there sitting under a 600w im usin a coco/perlite mix and a steady ph level

600w is a bit much for 1 and im sure youve overwatered

nope not a over watering issue sorry

The tips of the leaves have died too

Well yeah, they need nutes - mostly nitrogen when they are young and in veg. See, this is one of the reasons I hate autos - if you fuck up anything, there's no redoing it. With regular plants, if you stunt them a little, you just give em an extra week to let them recover and get back to size, with auto's you just get less yield =/

Too early for nutes the pH level was rather high to begin with well extremely high or is it maybe the chlorine in my water?
anyone have any idea why there doing it its getting to the point that im thinking they might die if left so please help hate wasting money.

I flush my coco with a light mix of nutrients a few days before dropping in any sprouted seeds. Then i run a low ph 5.8 to 6.0 and feed them every week. There is nothing in coco.
Start them out with that 600 way above them and lower it slowly, so they get used to the light and avoid them stretching.

If you are not that experienced with growing i`d recommend using soil. Coco is not for everyone.

i used coco for my bag seed last grow didn't have any problems till late flowering except awfully slow growth just like these are like 20 days old now since they broke through what would you suggest i do to fix this

I would start them on a feeding schedule, start slow and build it up in the next few weeks.

i gave them a light feed they are still yellow but seem to be growing slighty slowly there very small for there age even for a auto flower.

I prefer using clones in coco or hydro.

Dont expect miracles in 3 days. Just try to get them on a schedule, and see how they do after a couple of weeks. New growth must look nice and green.
