Agreed. Look at the plant on the right beginning to show the same signs.
Agreed. I do ph and use evaporated tap water. Here's what I have found. i experienced, and your experience may differ, is that during the early stage of life, first 4 weeks or so, my water is phd at aroun 7.3 to 7.5. What i discovered when the plant was young was that ph water of around 6.2 was hurting my plant. I think this is because there is a relation between acidity/ alkalinity and ph. The soil has a ph of a given value based on the TDS in its medium and when i fed with more acidic water the plant could not handle it. So i began watering with more alkaline water, again, 7.3 or so and corrected the issue. As the plant grew and required water to runoff i noticed that as the soils nutes became less, the runoff more accurately mirrored the input so i could now add nutes, ph to 6.2 and water my medium knowing what i put in would be what i got out. Soil has nutes ( tds ). Plants eat nutes ( tds ). Soil becomes neutral. Limited tds. Now you feed and balance tds and ph
I personally think you are way over doing it , go with 6.2 if your tap water starts off at ph of 8 then lower it to th3 desired level and don't mess with it , could be burn not necessarily a deficiency , sometimes deficiencies and burn can look similar if not rhe exact same , water with straight water at the correct ph and you should see some normal growth starting to grow back healthy,
As I said your experience may differ. Perhaps it's our soils or mediums. But what I have seen and deduced is that soil has a ph that will bear on the plant Moreso than the water you add to it, to a point. A higher ph , or alkaline water , has less tds than lower ph water. The plant knows how much to eat at the root level and only requires the medium be hydrated to allow absorption. Why would you water an acidic medium with an acidic water? Use an alkaline water for the purpose of hydrating the properly phd soil and let the roots take what is there to take. For the record I am not contending that he has nute burned his crop, but burn or deficiency, he's watering/feeding wrong and not understanding the relationship between ph and tds and how they interplay between medium and liquid is the culprit
What nutrients are you using? The tacking effect of your leaves looks like light burn. What is your light? Also the better of the two plants leaf veins yellowing looks like calcium. The omnipresent yellowing of the leaves looks like phosphorus and maybe potassium. What is your watering and feed schedule? Also, pot type and size. In the mean time here is a great 2 minute video I refer back to often.https://youtu.be/IiGzX6vTkhU?si=s09SrJIFNrhPvZQ1
Lol... Blight. @johnw6669 , careful , you may soon find yourself condemned to a 40 year trek through the wilderness.
the second pic doesn't look like a root/fungal issue to you?
