Don't let coco dry out, it's not soil.
Over watering? Nutrient lock out? Pics included.

never heard of that before. i didn't think microbes could "eat" nutrient salts.

pH was 5.8 and a plant that size would never starve at 1000ppms.

Look up the guide to nutrient toxicity / deficiency in the forum.....1000 ppms seems a little high that early in veg

OP said runoff is 1.5x ppm and ph is 5.8
It's a pretty cut-and-dry diagnosis imo.

I would say coco is more forgiving with under-watering than most soil methods... Over-watering is always worse regardless. People have a bad sense of when plants need water, that's why I always suggest letting the top 1/8-1/4 inches dry a bit before watering. I have seen many coco grows devastated by people who water daily or more, with no regard to the medium's moisture. There is obviously an optimal level of saturation a given medium should be at, but without a high-quality meter, your best bet is to pay attention to the medium.

Sure, assuming their plants are taking it up. A lot of coco grows water throughout the day in smaller amounts, which is likely the case with the grow you are referencing. And I am sure the system was built upon how much water was needed.
Point is, plants can only take up so much, if you water a plant that is already saturated you are not helping it. Especially if there is fertilizer involved, which leads to build-up. Plants should be watered to maintain optimal moisture, which is certainly not full saturation. Making suggestions to growers based on "I water this many times a day" is not helpful to anyone. Because the truth is different situations require different amounts of water. So, the best advice is to have people pay attention to how saturated the medium is, not how many times a day they water.

you treat coco like hydro so it's virtually impossible to over-water. and if you water coco to runoff each time and assuming your EC isn't crazy high, you won't get salt buildup

You still need oxygen in your root zone. Continuous watering in coco can cause a perpetual cycle of issues with under-developed roots. Leading to all kinds of issues with over-fertilization. I have seen it time and time again. It is one of, if not, the most common issue in horticulture across all crops. I can't tell you how much I had that said to me at school. I also wouldn't say coco and hydro are the same. The OP is having issues with over-fertilization, so I didn't think it was outrageous to recommend paying attention to watering practices.

Whomever is “ in charge “ of fertilization - should either get shown the door or knee in the nuts.

LMAO! Even hydro growers can tell you how important it is to get plenty of O2 in the root zone. Some even use oxygen tablets... At this point, I am going to assume y'all are just trolls, not horticulturists. I am sharing simple fundamental knowledge that any amateur should be well aware of. Anyone who cares to learn about respiration in roots, look into it. Every method of growing and propagation pays much attention to this fundamental. Hell, even the OP knows more than y'all based on the subject title... lmao

but you aren't aware that every time you water coco you add O2 to the root zone???? y'all aint no horticulturist, ya hear!!! lmao!!!
