Good suggestion, didnt think about it! Thats why its better to have as many people as possible helping

I feel you no worries! Ill be around.I have my eyes on the thread. I'm multitasking right now. I'll jump in when I can.
Dont you think its the high EC causing a lockout rather than the lights being too intense? He is feeding WAY more than enough hahaha. Also I dont see signs of light or heat stress. I guess this can be cleared by asking:Tips and stripes. I'd turn the light down. It sounds like you're feeding enough, but the plant still can't keep up with demand.
Lockout wouldn't be my first guess. I feed coco 1.5 EC and higher after the first week or two. Edge curl, taco-ing, and inteveinal yellowing all suggest too much light to me, but you're right...let's see what OP is running for light.Dont you think its the high EC causing a lockout rather than the lights being too intense?

What light and how many inches from the plant?
I have been adding Cal/Mag to each feeding.5.9 ph is fine in coco. That shouldn’t be your issue. I feed lower ph than 5.9 in coco all the time and see no issues. Where mine lands between 5.5 and 6.3 I send it and have never ran into a problem
Sometimes young plants can be hard in coco because you have to start introducing nutes so early. A lot of times when they are small like that I get some weird colors and they grow out of it. Idk this line of nutes but does it have cal mag of any sort?
Ok thanks! That is the EC of the nutrients in the water before watering. I have top fed twice and plan to turn my autopot on in a week or so.Oh man I just saw your EC, thats bad, thats more than triple what it should be getting. Is that the EC of your water with nutes or in the soil? In whichever case is bad. You dont want more than 0,5-0,8 EC when theyre still so young, as they grow you can increase to 1,5 and flor flower you can go up to 2 if they can take it well, you gotta read them to know when youre giving too little or too much.
What is your water's EC straight out of the faucet? It's often over-looked but its frequently very helpful information.Ok thanks! That is the EC of the nutrients in the water before watering. I have top fed twice and plan to turn my autopot on in a week or so.
I am using well water and the Cal/Mag is from Botanicare.More than burnt it looks like it has a lock out problem because when the veins remain green its usually that the leaves are not recieving a key nutrient. Are you using tap water? And the calmag from that line? (Im assuming youre using the calmag since you said your using the full line). Coco holds on to calcium a lot but if you over do it youre still gonna cause problems, it can only hold so much, and after that excesses can be very problematic
From google so I dont have to type:
Too much calcium in coco coir can cause nutrient imbalances, specifically leading to deficiencies in magnesium and potassium. This can result in stunted growth, leaf discoloration (browning or yellowing), and reduced overall plant health. While calcium is essential for plant growth, excessive amounts can hinder the uptake of other vital nutrients, disrupting the delicate balance needed for optimal development.
My water out of the faucet is at .4-.5 EC.What is your water's EC straight out of the faucet? It's often over-looked but its frequently very helpful information.
I realy apprecite your feedback and suggestions. This is my first run in coco using salts. I've only ever run organic living soil, so I have some learning to do, that's for sure!Also, alternate epsom salts dissolved into your feed water at a teaspoon per gallon every other watering. Since you're in coco, we'll be looking for the sweet spot between just enough calcium to supply the plant's needs without over-doing it. The epsom salts provides magnesium which you will need as you move through this issue.
Anyway, keep following along with @Eledin. He's covering the bases quite well. I've only been stepping in for clarity when I think something needs a bit more explanation. He's spot on with his observations.
I have been very careful not to exceed 400 ppfd. I am using the floraflex 700 raised up to the top of the tent and still only running at 30%.Dont you think its the high EC causing a lockout rather than the lights being too intense?

Lots of ways to grow, but for context...my seedlings are under about 120 ppfd of T5 at this stage.I have been very careful not to exceed 400 ppfd. I am using the floraflex 700 raised up to the top of the tent and still only running at 30%.

Ok. That's quite a bit lower than I've been running. I turned up to 300-400 ppfd after transplant.Lots of ways to grow, but for context...my seedlings are under about 120 ppfd of T5 at this stage.
Ok, good to know! I will lower it and see how it looks.Your approach with your light is generally fine if everything is growing well. However when things aren't, this would be a rule of thumb to follow ...
When you start showing leaf problems, dim your light. This slows things down to help give you time to sort things out. This is temporary. Once new growth shows you've fixed the issue, then you turn your lights back up.
All the light manufacturers' and influencers' charts notwithstanding, it's all about what the plants show us.Ok. That's quite a bit lower than I've been running. I turned up to 300-400 ppfd after transplant.
This is my first grow in coco. I have been using the same lighting techniques with an organic, living soil bed with no issues like this.All the light manufacturers' and influencers' charts notwithstanding, it's all about what the plants show us.
