Testing the sheep manure

Some bottom leaves are yellowing. Water her with plain water and noted that Ph is a little bit high (7.1) and the runoff EC is very low (was at 323 ppm). Thus, probably the plant is experimenting nitrogen deficiency. Water her again with the organic bat guano humus at 5 ph (dont have ph down, so I´m using pineapple cider vinegar and its probably not working very well) and an EC of 750 ppm.
