Love your grow sgyle And how you did your journal. Great job and you def show it in your actions and dedication In your pictures .
i do have a few solution overviews I think after looking at what you were talking about and having concerns . agree or disagree, just trying to give a viewpoint and maybe my view may help ( worth the try )
you said and asked on your “run off requirements” and how much. If your soil and actually can conquer salt issues . fact is you don’t need to do run off and compared to coco that def saves you on water requirements and the headache of requiring a bigger Rez. Coco retains and Inless you also get rid of the salt. Your fucked
soluction to this is a synthetic base would be house And garden drip clean. However going organic and a true salt eating bacteria and makes your reduction of intake requirments ethier synthetics or organics by 20-50% np. Plus a all in one foliar including wetting agent and sugars.
seagreen will conquer your salt issues and if applied at 1ml per gal once a week and adding Seagreen and can be used before even rooted clones and to harvest and I suggest hand water method the vs automation for just the bennie and organic compounds (only once a week) . You don’t in your pics show I are growing acres so it’s np and easily measurable per plant. So you xan easily know how much to apply after trials .
key with watering is to water enough they are fully saturated but no runoff if you have no salt build up issues .let dry out enough ,I suggest lifting same size container right after watering than lift per day and you’ll get by visual and lifting when.
once I started using seagreen in organics soil (super soil) or 70% synethtics , it works for multple positives and biggest gain is less nutes and it removes the salt better than lab grade and does such great organic pgr effects. I see results from that product within 24-72 hours . They love it

you asked about what are those spots and you suspected nute deficiency. It’s
calcium from my viewpoint and if it’s not maybe it’s a mold ( you’ll notice it infects like cancer and what ever it touches will get infected )

option 2 possible:the mold I’m referring to is
septoria leaf spot, even if not infected a huge suggestion if you aren’t but to everyone is treat your plants like a dr does per patient and always wear gloves and have hand sanitizer or 70% iso and clean your gloves inbetween your plants if you trim any , dip into 70% iso every time inbetween the removal or using of tools. many diseases and molds and virus are just transmitted by touch and if you can stop that your in such a better ball game as long as you don’t have pest that track the disease onto multple plants .
Leaf septoria, also known as yellow leaf spot, is a fungal disease that can greatly damage cannabis crops. Here's how to deal with leaf septoria on weed plants.

calcium is my first guess, I would add higher dosage of that and remove any spotted leafs if your plant can handle that and watch to see if any new plants and the current effected plants have reoccurrences of such.
reason I suggested 70% iso over 90% they have found for using such as long term exposed or spraying hands/gloves the 70% is more effective because it won’t evaporate as quickly .
Hydro guard ?:to save you money on same strain and way more in concentration why not use southern ag fungicide ? 2ml per 20 gal and apply every 2-3 weeks. 98%+ of strain per bottle . I’m good on hydroguard lol
