MAC Flurry - Penthouse Cannabis Co

Giving the plant to much nutrients, Canna Coco A+B says 40ml per 10 Litres of water = 4ml per litre of water each one (8ml all told) which I find is overkill on PPM. Between week 4 - 6 maybe even up to 2000 PPM, it got to as I found out exactly how to use my TDS/EC PPM meter, that week.. Small signs of nutrient burn on tips of leaves. I started on week 6 doing 15ml and even that is high on PPM. Settled on 10ml each of Canna Coco A+B per 5 litre of water so 2ml each one, per litre of water plus 1ml of Cal-Mag Pro per litre. Basically halved what the Canna Coco manufacturers recommend.
