Raise a dosage of CalMag. I would combine it with half dose of ur N source. Should be fine. Those dots signals lack of Ca.

Hello my friend, you provide the plant with enough cal-mag to prevent getting not enough. So you got another problem. And I am sure that your pH is a bit too acid. Give your nutrient solution with pH 6.5 from now and up your cal-mag to 1.5 ml per liter.

It's most likely microbial if you're providing cal mag already. You can give foliar sprays of Epsom and give more cal mag but I think it's an uptake issue in your medium. I would try and fortify your soil with some LABS to get things going aging in your medium and add water soluble calcium to your top soil with added Epsom salt foliar sprays every week.

Yep, looks like cal deficiency starting. Up your cal/mag dosage, can't really overdo it if you are sensible about it. Remember too, what is showing now in the leaves, is a reflection of what was occurring in the root zone 2 weeks ago. Damaged leaves will not recover, but new growth will be better.

Yes, this is the beginning of a Cal-Mag issue, but this is nothing to worry about because you're already giving the plant a supplement it's at a low dose try going up a ml or two and that should correct the issue.

Calcium deficiency can speckle with necrotic spots like your seeing there. Manganese will also speckle similarly. The difference between the 2 can be seen if you look closely at the shape of the spots. You can grab a 1 liter bottle of Calmag from your local store or amazon or where ever you source your supplies. If you are growing in Coco you certainly will want to add it throughout your crops life. 6.2 pH If you want, you can pulverize egg shells into powder and sprinkle it on the top of the soil and water it in. Calmag will act faster though, much faster.

Possibly the start. Keep ph in check Nutrient ratios in check Give a calmag supplement. They say epsom salts for the mag and sulfur and crushed egg shells for cal. Keep looking for answers. Amazon for calmag solutions and here and Google for the rest
