Brown rusty spots looks like nute burn help

hi please could you give me some advice everything was fine with the clones i grew them in veg for awhile as i wanted to fill the scrog or at least 70% but i decided to flip to 12/12 just before i flipped i gave the ladies a flush and added for the first time cal/mag at 10ml per gallon then 1 day later flipped and ive now got a really poorly burnt almost look with brown rusty like look the leaves have shriveled and burnt..... i think i may be a calcium deficiency or nute burn but ive not put any food in as ive used home and garden bat mix which contains enough food for 3 weeks etc early on i had spider mite which i cured completely with neem oil but they was beautiful and clean before i flipped any help would be great obviously any info you require i can supply although a man of your caliber would probably know via the picks thanks in advance ..........somebody pls tell me how to add pics lol

I wish I could tell you lol I ended up uploading from the PC but I put the pics on after I put the thread on...... The soil as I've already said is house and garden bat mix and I ain't used any nutes yet? But either way when I use nutes I have fox farm tiger bloom

you burnt the shit out if them. Cal/mag is recommended at 5ml per gallon, you used double.

Hey Mad, Go back to where you first had a problem, from the shine on your leaves it looks as if your Neem mixture is a bit rich.

hi mate thanks for your response yeah i was thinking the same with the cal mag but it says on the bottle 2/3 teaspoons per gallon so i put 2 teaspoons in which equates to 10ml and i made sure it was a teaspoon and not a shovel lol ive been doing autos so ive been very careful with the nutes with these fems the only thing i can think of is there is a mixture of soils in the pots (coco pro mix i think) and the bat shit was used to get the clones routed and added to the top i think im going to persist with this grow and see it out then ill get brand new bat shit and replace the lot ive ordered a bluelab ph tester and a cheap ebay one as a backup aswel as mine is broke although the ph is good in my area
but if anyone can identify whats happening as im sure theres more than one issue ill use this as abit of training as i hope ill never get to see them again lol

ohhh and same with the neem oil i used 2 tablespoons of neem to a gallon of water i sprayed all underneath first due to the leaf drooping making it hard to do then the top i repeated the same process (just before lights out) a week later and that was it for the neem i haven't sprayed for about 2 weeks but before the cal/mag add they looked great maybe its just sensitive as the one in the back left corner looks beautiful .... ive researched for hrs anything i want to do before i actually do it but the spider mite issue is completely gone i also used predatory mites i dont know which did best but i think the neem did the most killing and spider mite can never get immune to neem as there needs to be a survivor to then reproduce to become immune but there is no survivors the first spray killed the live ones and the 2nd spray killed the hatched eggs neem is also synthetic so its absorb into to plant protecting the whole area...also good for drench to kill knats and root rot anywayyyyy lol sorry i can go on when i get started now im going to have to roll a joint and spend ten min checking everything ive wrote for spelling mistakes )))

I think that is to much neem. Sure you read the directions right?

there isn't any instructions with the neem most was putting 6 tablespoons per gallon but me being on the safe side went with 2 as i didnt want to suffocate or block the hole in the leaf cant remember what its called and kill it im trying not to love my plants to death....... normally with nute burn the leaf goes brown and falls off these have rusty spots but not acting the same as nute burn

if you meant calmag ill get the bottle or better still ill take a pic after ive treble checked it lol

well i dont believe it proper masive school boy error after taking a pic and zooming in to rediculiously small writing it says 1/5tsp/qt which is what i seen and rolled with it but now ive read the whole line now that i can read it and it says 1ml to every litre ( ill upload a pic but fair play for sticking to ya guns high five there pal now whats the best thing to do now its in flower ive already 2 days ago flushed with 20litre of water and put just a small drop of root stim for stress and foliar sprayed lightly with epsom salt and ive done nothing since as i want to let it dry and recover

I had the same issue. Too much need oil and I fucked myself. The girls look just like yours. I had to pitch them. Sorry for your list. Sucks big time..

yeah mate its all trial and error ill get there in the end lol
