Deficiency or Burn HELP PLEASE!

Hey whats up everyone. I am a new grower and man do I have some problems. I will start off by saying I made plenty of mistakes but I'll just start with whats going on now. I am growing in coco coir. I been feeding half the nutrients and PH at 5.8 to 6.0. Here are some pics of whats going on with my leaves. Someone help please I don't know wtf is going on and I don't want my plants to die. I am just starting 2nd week of flower. Strain is Blue Pyramid. Here are the pictures.

What’s your ec/ppm? How often are you watering/feeding?

ppm going in is at 650-700, coming out its at 1000 to 1200 ppm. I was feeding once every 4 to 5 days.

Plants in coco need to be fed daily with the optimal situation being a smaller pot say 2-3 gallons recieving a few feeds per light cycle.
When you let you plants dry out the salts are concentrating as they are coming out of solution with the h2o. Then when you run fresh solution, all those salts are being picked up in the run off and your PPM shoots up. The roots are sitting in that salt, and water is being dragged out of the plant by a concentration discrepancy and you leaf tips are where that water is coming from. Also you get a situation now where the plant can’t take in nutes because the water is flowing OUT of the plant not in!
Not sure what your ratios are but your ppm is good..make sure to read H3AD’s sticky in the coco forum, good stuff.
Run nutrient solution EVERYDAY!! You need to provide oxygen and total coco saturation DAILY! Always run nutes in coco! The ONLY time to run regular water is in flush!
Get in the mindset of coco is hydro...
Start running fresh nute solution daily till run off is pretty much coming out what’s going in and I think you’ll be fine.
Read DJM’s sticky in the coco forum coco trees.
Good luck!

No Problem!
What’s the plan? What nutes regiment are you using? What “strains” are you growing?

How is she doing now, I am curious about that Blue Pyramid. Post more pics.

She recovered and came back great. I have them drying right now.
