Emergency! What is this?

Nutrient lock out. Google nutrient lock out pictures. You will see your pictures there. Iron also might be to much, or to little. FLUSH them a couple times. If you get them green again you will be lucky. More likely you'll have to remove the effected

How wet is the soil? When was your last feed?

Are you feeding through bluemat system?

Is there no diary attached to this? Don't give VPD; give me temperature and humidity separately, also, what's your night RH going up to? There is just not enough backdated information to make even an educated guess. Anytime anyone says: "PH is around" then I assume they do not know PH and didn't actually check. Could be as simple as a mineral salt build-up drifting the pH towards alkaline, then the worst thing you can do is add more nutrients until certain. When the green is effected on a plant all over and it's anything but uniform then its micronutrients. But first, we need to identify the root cause of why those micronutrients no longer uptake efficiently, is it because there is no nutrient in the soil or has the pH drifted above 7 out of optimal range for some nutrients? Ph ph ph then message me we can go from there, logic dictates we must remove ph drift as a possible cause, and once we do we can proceed with the problem at hand. Until then anything beyond "micronutrient" is a wild guess. High pH levels can make it difficult for plants to access nutrients like iron, manganese, zinc, copper, boron, and phosphorus. These nutrients are important for plant health and help with functions like chlorophyll synthesis, enzyme activation, and cell wall formation. Visible Symptoms Plants with high pH nutrient deficiencies may exhibit symptoms like interveinal chlorosis, bleaching, pale mottling, and blotchy or marginal necrosis of new growth

almost forgot, basalt will also provide your plants with silica aswell for health benefits, just make sure to get the ultra fine dust and i recommend moistening it before applying it to the soil as you dont want to breathe that dust in or have it flying around your plants.

I think your plants are missing nitrogen, potassium, calcium, magnesium, sulfate & some phosphorus aswell. Also they probably need more water. I recommend adding some kelp meal for nitrogen and potassium (ascophyllum nodosum) and raw gypsum (calcium sulfate) + basalt rock dust (mainly for magnesium, but also has many micro nutrients like iron, copper, zinc, etc) Good luck!

They do look severely underfed and underwatered. This myroterra fertilizer seems to be low especially in nitrogen and potassium, i cant find any information about calcium, magnesium or anything besides the basic NPP (4/4/4)
