Burnt tips, Brown spots & discoloration.

My two black mamba clones are having issues with what seems like nute burn on new bud growth as well as older fan leaves followed by brown spots & purpling underneath and on top. Not too worried about purple as it’s suppose to with this strain. Using mix of miracle gro organics, Fox farm ocean, worm castings & part coco coir for soil. Only used two light feedings of Dr. earths organic bloom & last feeding half dose organic cal mag. Run off is 670ppm & ph water & runoff 6.5-6.8. My Pineapple Express is doing great with same feedings as seen in pics. All these symptoms combined with yellowing throughout is really confusing me. They will be 5 weeks since switching to 12/12 cycle tomorrow and all from clone. Any input to help stop burning would be great. Running 400w hps, mars hydro 1000, side cf’s and two fans, one oscillating. Temp around 77 & humidity 47. Temps at night drop to about 67 & humidity rises to 60. Have heat Incase drops too much. Thanks

Ya have few different problems going on there . . Looks like this should of been corrected ALONG time age . .

Maybe started out been ph issue but then looks like ya have locked out others over time . I would give them a light feed say 1 ec and run a shit load through them . It won't repair the damage and it won't increase the damage but ya should get ya ph and ec in range . Ya want to be dropping ya ph to 5.8 - 6 . Ya plants will take up more P and K in that range .
Ya have a canny mix of different medium there aswell. Maybe having all that shite has been the cause of ya problems. You really should (KISS )

Thanks. Yeah, I really screwed up most of it’s life feeding untested tap until symptoms showed. Once I bought a meter my tap showed 8.4! ‍Thinking the pineapple was doing so well maybe it was genetic but it got really bad quick.

8.4 for tap water is ridiculously high .

Brother...you're running into nutrient lockout ...get some PH down to around ( 6.2-6.8 ) I would flush your plants with 5× the amount for pot gallon size. And I would brew a tea and hit it with everything...kelp meal, batguano,earthworm castings, Molasses to help the microbes eat up in return will help your roots uptake faster. Maybe even add some recharge if you have...Good Luck & Happy Growing !!

Sounds like a plan. Thanks!

sounds like a bad plan. I think that miracle grow is your problem. to flush and return with that stuff won't help. but do you what you feel is right. You shouldn't have to give any other fert like dr. earth in those soils as it's way too much now. Just go with lightwarrior when their small and ocean forest when they get a little bigger.

Depending on his ratio...however if he flushes he can drop the ppm and start top feeding by the tablespoon....just my thoughts you dont have to listen to me I'm not a professional just giving my advice ! Good Luck & Happy Growing !

What's the point of dropping the ppm if the grower top feeds by the tablespoon? Doesn't that replace everything that was flushed out?

Just an option Tbh...I've done this process before & its worked for me..I dont understand why some of you think your 100% cannabis growers when there are MANY ways to solve issues and grow cannabis...you dont like my opinion then don't use it...he was asking for help. If you have a better option then why dont you help the guy out instead of sitting on your couch tugging your dick and being an asshole. I wouldn't listen to shit Trickydicky says cause he doesn't know how to grow cannabis.....TBH....lol some people rather talk shit from their cardboard home then help a cannabis grower out. FUCK THE HATERS TBH TRICKYDICKY....

hahahahahahaha keyboard warrior .
All I said was wouldn't listen to this opinion tbh .
What is wrong with that .
If you take that to hart and start rambling shit on ya phone cos the paranoia has kicked in making ya brain work overtime .
Go and play with ya marbles
DOYLE

Some people are sensitive. You bruised that ego.

I wouldn't laugh, jonny, I was referring to your ego, in case you didn't understand. bizarre response. you're an aggressive communicator that will say anything, aren't you? pathologic communication style, huh? And always full of shit too. BTW, it doesn't do any good to flush 5x pot size, then "hit it with everything" as you suggested. To flush and then replace everything flushed out never makes sense. But I get the feeling that's just a typical day for you.

That's typical behavior for aggressive communicators. They talk and talk like they know what they're saying, but if you know the facts you can see that person is full of shit. Unfortunately, these forums are a real breeding ground for those idiots to bring their nonsense to the rest of the world. They're always trouble that way. Naive people will listen as they don't know the difference. You have to protect yourself against things that sound good on the surface, but deep down it's all bad info. When questioned, they respond with defensiveness and anger at being disbelieved. So predictable when you know what to look for.

Haha. Well, that escalated quickly.. I appreciate the passion on this forum.

the ocean forest and castings is probably a lot on its own, casting especially can run hot depending on their source
