Leaves Curling and a Bit Leathery

[nevergetsold]

I'd wait on liming the soil till the water ph and runoff is known. It might take the ph further out of range. Limestone dust (lime) has a ph of around 8.

Do you use Superthrive, or are you adding any micronute formula's? (CalMag, B-1, Botanicare Sweet, molasses, ...)

Finally got the Hanna pH meter calibrated and the tap water pH is 7.5 and the runoff is 7.3. From what I have read 6.8 is better but I don't know if my readings are high enough to require intervention.
