5 Star Killer and 1 BC pinewarp x bubblegummer
I'm thinking transplant shock but not sure since I saw this on a previous grow in soil. The new growth doesn't have it and the older growth looks fine. 5 plants (star killer) have this with about 10-14 leaves total throughout, half way up. Super soil, no checking or run off- in veg, room is 73-77 degrees usually around 60-70% rh. Water every other day at this point. Anything I left out?

it starts out blackish blue and grows slowly to this, never has a halo

Hmm could be the lights your using, lots of far red? You may want to ask dangerdan about it, but i was taught that too much far red lighting can cause very unusual symptoms in cannabis plants, it also looks like a magnesium deficiency
 
Rosettastoned something very similar happens with some of my autos in super soil about a month before they are finished. This morning I gave 3/4 dose of calimagic I had from a previous grow, they seemed more perky(hands were up). So I'll keep an eye on em and see how it goes. Did it progress slowly? Or happen quick ? Mine happens slowly.
Good luck
 
It's supersoil so you may just want to get a little run off, just enough to check ph. I'm guessing the problem is isolated on a few leaves and doesn't spread? The problem may correct itself but if it spreads I would check ph.
 
Morning RosettaStoned, I don't think you got nothin to worry about, a little Cal-Mag, , ain't gonna hurt nothin, and it might fix her up just right.
I wouldn't worry about that ,unless it started spending, but I think the Cal-Mag will fix you up.
In supersoil, you can't really mess up.
Unless you don't water them, !!! Lol
 
It hasn't gone any further than those leaves, and that happened shortly after a transplant. Was just kinda wondering for the future. I have two different pHs of water, Ro around 9 and tap at 7.6ish. If tap is too low then I use RO.

on another note, IF I were to use Epsom salt to cure a mag def how much would one use in a watering?

as far as far red, that's really only in my flower room on the cobs. The one vipar remodel has two far red monos but at .7 A they are not very powerful, not enough to do that at least.

thanks for the help ya'll
 
If they're not flowering you can try a foliar spray with the epson salt. At 2tbl per gallon it should easily uptake with a foliar feeding. You can also make a tea with some langbeinite or epson salt with a tbl molasses if it is in flower. Langbeinite is water soluble and won't effect ph.
 
Yeah looks to be localized on older shaded out leaves. I used a foliar spray of epson salt when I suspected mag issue on my gg#4s and top dressed 2tbl langbeinite.
 
Thanks for the input friends. I think it partly my watering practice and partly my soil. I'm going to water less quantity and increase frequency. Sunshine mix advanced #4 is more coco than I thought. I may have mixed it a little too porous as it dries out fairly quick.

Also may have waited too long to put into 12/12. The sides of the pots feel firm like to roots are filling up any extra space. I topped with compost and mykos. Worked in a touch, watered thoroughly.
