well mate im surprised there alive,750 to 900 ppm ,what ,more along the line 400ppm at 6.0 ph.
are you feeding daily?
what is your water source,tap water ,distilled ,ro?
what size are those bags
I think you are seeing the results of a lockout condition from too many nutes. I'm saying this because of the twisted leaves I'm seeing on the tops as well as the amount of fertilizers and stuff that you are feeding them.When you have Ph swings and fluctuating conditions, the soil can easily lock out nutrients. Too much cal-mag can raise the Ph and lockout magnesium, but the curling leaves look more like excessive Potassium or Phosphorus.
ok so i must be confused,are you growing in coco?I feed them every watering, which is about every 2 days, maybe 1 and a half depending on how quickly they dry out. I'm using tap water and they're in 2 gallon bags.
Also, I wanna add that I was giving them around 500ppm (was slowly increasing as they grew) before I started seeing the issues, I just thought it was an issue with calcium, as I buffered the soil only once instead of twice, so I started giving them a ton of cal mag, which made my ppm skyrocket.
Yeah after reading what oldskol wrote and seeing this, I think you guys are right. I think they might be over fertilized and the nutes are being locked out.

What would be the best way to fix the issue? Should I just water them with 6.0 ph water and wait for the nutrients to get flushed a bit or should I give them a little, like around 200ppm?
Yeah they're in coco, I rehydrated coco bricks and buffered it in a cal/mag solution for around 10-12 hours.ok so i must be confused,are you growing in coco?
there is your problem mate,coco has to be watered every day,never let it dry and never just water alone,so i asume you have a pretty good saltYeah they're in coco, I rehydrated coco bricks and buffered it in a cal/mag solution for around 10-12 hours.
They originally started in soil, but I switched to coco when I replanted, I'm liking it, but I'm just not sure how much nutes they should be getting.
im refusing 3 waters a day right now hahaha,you cant over water cocoI second (and third) what has already been suggested. Seems like a simple case of nutrient intensity/ watering frequency.
I don't think this is what you're seeing in this case, but often calcium issues in coco aren't caused by lack of calcium is solution/substrate, but instead difficulty in transporting calcium to new growth. It's all about depth/frequency of watering.

buildup,let it dry does that ,it only is what you put in it mate.
firstthing you need to do is feed at 6.0 ph and from looks of those plants 400 ppm ,feed it to a real good runoff,catch the runoff as soon as it comes out,just catch enough to check what first comes out of pot.once you catch just enough finish letting it runoff at least 20% mate.do that and let me know what your runoff is for starts
The beauty of coco is you can flush effectively - and restart. Flushing with ph 6.1-6.3 plain water water on a cycle or two and then starting at ~300-400 or less and this would turn around pretty quick, IMHO.
What is the ppm or EC of your input water ?
shoot for what you put in or damn close,then leave it alone and feed as normal with plenty of runoff and you wont have to check none that stuff ever again,unless you have issues again.They're getting decently big, I'm not too sure how many weeks out they are since the start of my grow was a bit wonky (didn't have a tent or light first few weeks).
Thanks for all the info, I'll continue flushing it and see where the ppm's at and go from there.
Thanks! I'll definitely keep note of that. I'm in the process of getting the ro to around 400 ppm right now.Just another small pointer : if your medium does get too dry, don't rehydrate it with a full dose of fertilizer. Instead, consider using a mild dose of cal mag to bring it up to full saturation, then resume normal fertigation with the next watering.
