purple stripes on Chesse auto?

Hey peps.....got a couple autos rolling a cheese and a Super skunk......they both popped threw the soil Dec 3 in roots organic emerald mountain they have only had 1/4 strength nute feeding once the cheese has purple stripes going up the stock and some of the leave stems are purple there is also a couple necrotic leaves not bad but a couple 2 or 3 leaves have it. What could the purple stripes be? Soil ph is 6.4 temps stay between 80 and 70 71 threw the evening.

Given the plant is otherwise healthy, has correct light, have you considered magnesium deficiency? Usually becomes evident about a month in, purple stems on the top green underneath, the veins on the lower (older) leaves can darken to a purple and the leave start to curl inward. Check some videos online that show plants with mangesium deficiency and you will see if it is the same. Better to see a video of another plant with it. Those stripes look different though because they are on the sides where with mag the tops toward the light are purple and the undersides are green.

I'd be looking into your night time temps

often they fall more than you realize

but it looks good for now

I can see theres some low ryder in this strain

and suspect Vision or White Label seeds are at hand?

lol

H.S.O UK Cheese AND ILGM Super skunk....my night time temps don't drop below 70 degrees.....autos are fussy little fuckers....doesn't even seem worth fuckin with

Spray some mag on em for a while see what happens

I just gave straight water with 2 tsp epsom salt per gallon....if it's mag it will perk them right up in a couple days I'm hoping
