This is Pissing Me Off

Hey guys, thanks for reading!
This is my first ever fully coco run. I'm using botanicare nutrients and FloraFlex lines.
Two plants (of 6) left. One is showing what I think to be a really bad nitrogen toxicity, the leaf ends are very curled under and some are slightly burnt. The other plant is loving its environment and water schedule.
I am watering 3 times a day @ 615ppm and 5.8-6.1pH. Silica, Calmag, Liquid Karma, Hydroguard, Grow... 2 minutes per event, good amounts of runoff.
I've flushed the affected plant 3 times now with 400ppm water with just Calmag and Grow. I managed to get the runoff ppms down to equal of my input water (400ppm). Its starting to show a Calmag deficiency but no signs of improving from the nitrogen.
Will the claws go away after the plant recovers? I cant find an answer to that anyfuckingwhere!!
Any advice is welcome and Ill answer any questions the best I can.

Sometimes mild claw will go away, but sometimes it lasts forever on those leaves. Sucks, I hate seeing it on my plants too. Since you're multi-feeding, you prob just don't need that many PPMs for the plant size. You backed off before any real harm was done though.

You can overwater coco, I have done it. Maybe water 1x a day until roots are fully grown in. Less ppm too I think.
I'm new at this to.

I thought this might be an issue so I've only watered the problem plant once a day for 3 days now. It doesn't seem to have changed and for a week or more now I've seen roots poking through the sides of my pots all over, so they're grown in for sure. I'm also using botanicare's "aeration" coco, which has a ton of perlite in it so I could do those multi feeds. What's really getting me is that the other plant is glowing like no plant I've grown before...

Just did another watering (basically a flush) of 425ppm water- came out at 328ppm.. so it seems like shes feeding from yesterdays watering. Runoff yesterday was 385ppm..

This shits starting to confuse me a bit. I know I'm overthinking but I'm just kinda stuck.. pH and ppm are (from what Ive read about multi feeds) perfect, and it shows in the one happy plant.

Ill run the lower ppm once a day and see if that helps, that's the only thing I think could.
If yall have any other ideas lemme know!

Much love and happy growing

Nope, Feed all nutes, every time in coco to a decent runoff. 20% of what you put in should come out within 5-10min.
You runoff ppm will usually be a bit higher than what you feed, if it's lower something is eating, the coco or the plant? idk.
If the runoff ec gets 300 or so higher just feed more ml or more frequently not more ppm.
Only feed more ppm when the plant looks hangry.

I haven't tried this yet.

i'd drop your ppms and increase your pH

are you sure your ph an ec meters are running good? my ec meter was missing a metal electrode , so it was flying blind on a cycle, till someone commented about my lockout probloms, he said to check my ec meter, sure enough an electrode was missing

what are your temps in the tent too?

Second that. Natural pH of coir is between 6-6.8. When I was running coir I had the best results with trying to aim for a pH of about 6.4. I consider everything between pH of 6.0-6.8 acceptable in coir but would aim for 6.4.

Sweet so I can up pH and lower ppm next watering. What ppm should I be aiming for, like 300? Mixing my nutes at 1/2-3/4 gives me about 620 ppm

i feed mine 1x a day in dwc at 0.5 ec net 250ppms. the more times you feed per day, the less you need to feed.

I guess I need to look into an RO system.. my water comes out of the tap at 120ppm. Getting to 250 with my whole recipe seems impossible.. that’s what I’m at with just calmag and silica!

Temps run mid 70s up to 81f during the day, high 60s at night. Never drops below 67f at night.
RH is 37-47% depending on the day.

Yeah, I have a bluelab pH pen I calibrate religiously. The TDS meter is one of those cheapies off of Amazon. After I sell a couple oz my next big buy is a nice TDS meter.

The only other thing that really helped me was getting temps and humidity right was using ro water. Not everybody needs to use ro water btw.
I do though and it made a big difference in all the plants I use it on and the residue left over in the drain pans as well.

Check out this vpd chart, pretty important. Watch the mouse on the leaf temp selector and make sure you are using the right one. Honestly Idk how to get anything different that air temp with my led light.

I picked 50 rh for my lowest because that's the lowest I can reliably get. SO by the chart 75~78 is a good temp for me in flower. If I were vegging, I might go warmer and higher humidity if I could maintain it. I can change my temps way easier than my rh.
