He is watering at 5.8, lad's just bought himself a shiny new PH pen.
We had a whole discussion the other day with Jimmy about 0.1 PH being 10 times more/less acidic/alkaline because of the scale used.
So if the medium is supposed to be 5.8 but it's actually 6.2 then yes that's very bad, it's 40x more acidic than it should be.
If you look at this chart (the most comprehensive I have found).......

.......it shows that at a PH of 6.2 in hydro (coco) then only Nitrogen, Magnesium and Sulphur are being uptaken by the plant and Phosphorus, Potassium and Zinc have been locked out completely causing more problems.
The cause is not paying attention to proper PH, the solution is to adjust what you put in so that it 'neutralises' what's in the medium.
It's the same principle as making a child drink milk after it has swallowed bleach, the milk neutralises the bleach.
