Is dosing potassium once a week via seachem premier water softener ok? I add excel and seachem flourish and iron or daily, should pottasium be daily too?
I will be planting more heavily very soon so will look into seachem nitrogen
You can get Magnesium Sulphate AKA Epsom Salts from the chemist or health food shops. I usually get mine in 100gram tubs from Teach chemist off the shelf.I understand what your saying makes alot of sense, I'll get a third led light which would bring me to just over 1600 lumens meaning I will have 23.5 lumens per litre according to tropica that's enough for medium plants, I'll keep dosing the excel see how it goes and I've been looking at magnesium dry ferts that you add to distilled water and dose accordingly as all ferts lack magnesium
