LA Peyote Kush Quadline w/Timber COBs

Weeks start on Saturdays, so today is the start of week 5 since 12/12. My maintenance plan is as follows….. Daily: fill reservoirs with 1250 ppm nutrients / 6.3 ph Weekly: check reservoir ph and ppm levels Every other week: empty and clean reservoirs Sunday: observing some deficiency on the lower leaves, guessing potassium deficiency based on grow weed easy resource. Adding 5ml/g of liquid koolbloom to feed. Wednesday. Adjusted reservoir ppm. Was at 1610ppm when I checked it and 6.7 ppm. Added lower ppm mixture and RO water to lower reservoir ppm to 1250. Topped off reservoir. Seeing a potential potassium deficiency on this plant too, so adding back liquid Koolbloom at 4ml/ g. (0-10-10)
