What deficiency is this? Help

[Treeibus]

Hey guys I need your help. I have 2 Northern Lights Auto on day 46. I'm having some deficiency that im not familiar with ... I'm thinking cal-mag? Any help would be greatly appreciated

I might not be much help diagnosing but I know it'll be easier for some of these other growers to help out if you provide more info like what medium, lights, temp/rh, nutrients, watering method etc.

It looks kind of like potassium deficiency but I'm a novice so take that lightly.

I'm growing in fox farm ocean and using down to earth nutrients 4-8-4 and cal-mag 2 times in 46 days. thanks @Sangmang i dont know why i didn't include all info i was in a hurry. i water every 4 -5 days as needed with ph 6.30-6.80 I use a Maxsisun 2000 light

could be cal-mag or even wet feet, think I would try plain water & cal-mag on your next water cycle, also might help to remove pans and put an elevated grate under the bags for better airflow & drip drainage.

If you lift out the grow bags is there a small puddle? Generally speaking it’s not good for them to sit in runoff - I know many do that but since you are having the start of issues I would jump on that. Plant elevators or raised grating can’t hurt getting more airflow to the roots. Weed roots love air but not light...

My Ca deficiencies always manifested themselfs on growing leaves at the top or at mid level with a lot of light hitting them. This seems to be too low and too much in the shadows for a pure Ca deficiency.

was thinking mag more than cal but epsoms will do that

well I have added cal-mag and gave her a little more 4-8-4 down to earth food. she seems to be getting worse. I'm not really sure I don't want to do anything else fearing it will be to much for her to handle if I'm wrong... does anyone know how long Northern Light Autos usually take to finish? I'm on day 49
