Advice on the leaves?

[kann9]

Hello,

My Grape Ape indica has a little orange on one of the leaves. I don't know why. Don't think it's nutrient related because I use technaflora food. Does it do that if my grow tent is too hot? The temperature is around 80 degrees and humidity is around 30. It gets to 70 during the dark 6 hours, but 80 is the high. Advice?

Looks like a phosphorus deficiency

Or it could be a magnesium poblem. Its hard to tell between the two with that purple light on. I would check out the chart but also do more than one research to narrow it down to the best answer. Thinkin its one and its really another makin the problem worse wuld suck

If you have not already, be sure to flush well before doing another feeding.
