Can you check my plants and is my runoff ok day 30.

and here I am to say the opposite of everything... first, pH control is only necessary with mineral fertilizers, and it seems to me that you are using mono magnesium from cane, and that is the only mineral you use, and magnesium is better absorbed by the plant with a range of 6.5-7.5 more or less. when using organic fertilizers, it's not the pH that helps absorb nutrients, but the mycorrhizae that break down the nutrients and give them to the plant; the plant, on the other hand, produces carbohydrates that it exchanges with the nutrients from the mycorrhizae. so the result of the runoff pH is not a number to rely on. as for the administration of organic cal mag and mineral magnesium, it can lead to imbalances; calcium and magnesium always go together like two married people, but if you add more magnesium, the couple has problems. now you might wonder, but if they also make pH- bio, it must be useful for something; let's say it makes money, and the regulated pH, even if not very useful in organic, doesn't cause problems.
