@archie gemmill was around earlier he might move it to the infirmary if you want? Probably get a better response over there

 

[cannadabis]

is there anyway to edit where I posted the thread?

Looks like calmag, but I’m a noob. @archie gemmill will get you moved to the infirmary.

Can't be Ca/Mg, it's either Ca or it's Mg.
On this picture above it's Ca deficiency.

hi and @cannadabis coco medium is ph6,soil medium is more like 6.5ph.off ph can look like deficencies.too much N very dark green can lock out cal.
cal is the lil rusty spots,mag is a pale blotchyness between veins.often lumped together as they are often lumped together in the same bottle.
im relectant to move this over to the infirmary,cause i might get shouted at.the infirmary peeps like to do a good job,they are hampered from doing that if they dont have the info they need to start with.
this is the info they like https://www.autoflower.org/applicationform/infirmary-admission-form.2/form fill in the details and post new thread with the details here https://www.autoflower.org/forums/autoflower-infirmary-for-sick-plants.90/

@archie gemmill I have been watering my plant with 3.5ml of cal mag along with the gh nutrients per 2.5L of water, is that not enough cal mag to prevent a calcium deficiency? The mix I'm using has coco, worm castings, peat moss and volcanic ash that being said should I treat it more like a soil and water at 6.5 or keep it at 6.0 ph? thanks

 

[bad dragon bzzz]

just read agian northern lights week 10 whats wrong with NL that so many take so long to
i thought it maybe soil but its coco ph is fine but has 30 days worth of amendments,well used up by now.pretty dark green could back off on the N a touch stay where ya ay with cal/mag.
update in a couple of days with a few more pics,if its worse il move it over to the infirmary.
good luck n keep er lit.

Hey @cannadabis and welcome to AFN... looks like @archie gemmill has got you covered on your issue's. Simple calcium diff and very easy to fix... On you next grow I would recommend that you feed Cal/Mag at least once a week in soil when growing under LED's. Some plants will need less and some will need more, just keep an eye on those rusty spots, soon as you see them up you cal mag... The tricky thing is to know when to stop using it so you don't over do it on the nitrogen at the later stages of flowering, To much nitrogen will effect yield and growth later on in flower.

Need any more help just tag me (@Slater) and will do my best to point ya in the right direction

here we saved ya some on the welcome joint, have fun...

@Slater I have used Calmag every watering on this grow , that would explain my dark green leaves and nitrogen burn I got earlier, but why would I have a calcium defficiency if I have been constantly been using the cal mag?
