Deficiency ? Several pics. Plus info

Can anyone tell me what's happening.
Coco and perlite
Using mega crop and i add a little kool bloom, mammoth p and (silicon first before i add anything) then i add a little earth juice bloom to bring the ph back down. There was an issue with my pen and i might have been feeding at a really High PPM and PH could have been whack.
Bought a new pen and i make sure i go no higher then 1.2 ( 1200 PPMs) and i keep the ph between 5.7 - 5.9.

Those look burnt to shit imo

a 1.2 isnt 1200 ppms a 2.4 is 1200 ppms on the 500/hanna scale. Dont know the ph for coco but it might be the same as dirt which you should water in at 6.5.

Yup burnt up. Your gunna want to flush the shit out of that figuratively and literally. Renute at a much lower ppm raise your lights up if they are too close // slow the grow down a bit to let them recover. Definitely get some microbes rocking in your coco // hydrogaurd. Maybe some enzymes for a couple of waterings.

Lol ya 1.2 ec. 50 ppm per 0.1 ec so 1.2 ec is 600 ppm. Your ph is fine.... Maby. Have you checked your run off? Coco is ment to be fully saterated to 20% run off ever day, 2 days at most. If your coco is drying between feedings salts build up fast. Would bet if you check your run off its 2000 to 2400.

Coco Casualty #91284. What the hell is the appeal to less experienced , or inexperienced, growers and coco?

I want to know what the ppm they fed it at 1.2ec or 1200ppms.

Right! Lol ran a hydro store for 3 years and im a second generation farmer. Loved the results but feeding every day for 3 months was WAY to mutch work. Now i just mix coco in my medium

Worked on farms and ranches. I've run soil, hydro and perlite mixes. Nothing about coco except aeration in peat appeals to me. Newbies? Soil is a no brainer. Treat yourselves to growing cannabis and watching it. Instead of posting problems .

Oh shit.. So i have the Apera Instruments PC60 when im on the TDS part and im at 1200 ppm it says 1.2.
So im not supposed to go higher then 600 ppms ( i remember reading heath robinson saying 600ppm and everything higher was useless) but i see everyone say 1.2 so i just went with that.

So 600ppms is right ? and i burnt the fuck out them ?
