Back again with my auto

Got an auto going under a blurple 600w led recently upgraded to a 100w prakasa cob (mon the talk) in flower now looking Like shes at the end of her life, it's a shite attempt of a plant lol but she's getting that rusty look, hoping you guys can let me know what's going on, she's in soil and being fed old timers grow at 1ml bloom at 2ml per litre, she hasn't had any pk and she's had 0.5 cal mag aswell for good measure the last 2 feeds

when did she start to yellow? very slowly over weeks or over a few days?
from the top or from the bottom?

looks like mag toxicity hence the questions

From the top down over about 4 weeks id say, i thought I was keeping on top of it but obviously not haha

cal/mg into a living soil does damage over weeks if it's repeated enough times with a strong dose until the soil becomes toxic,
mg/cal is only needed in trace amounts in any good organic soil, i use 1ml per grow at most - 0.5ml into 2lt of water when i see the magnesium deficiency usually around week 5-6 of flower
that's more than enough for me

flush your soil asap and feed again at a reduced rate, they'll be hungry
you won't save those damaged leaves though, all you can hope is it doesn't spread down anymore

millwall had the same problem and his plants are pure banging now
so don't sweat it AA

I thought the exact same, although I've only fed the cal mag the last two feeds and it started about 4 weeks back looking like a mag def, she isn't too far off finishing anyway so think il just give her water from here on out an chop in 10-14 days and crack on with one or two of these cindys, cheers for the advice man

looks identical to millwalls, if in doubt flush them out

his plants bounced back in a few days,

infact they ended up with giant colas at the end, might be worth a try to get some more ripening b4 u do cut/chop

Second what Monster said AA. Give a good flush, a few day later a voila happy girls again. The proof is in the pudding. I wouldn’t leave them 10-14 days. If you put the effort in mate you will get rewarded.

stick the plant in the bath tub and stick the shower head on top of the pot. get it warm initially to melt any salts/ nutes out then get it to around 18c-20c to not stress her. Follow that up with a feed of reduced nutes. jd quite easy to do like that. i used to have all these buckets of water around for flushing to get the chlorine out, but i dont bother any more.
