@ThatGrowGuy, sumo boost foliar is at 2ml/Litre. No changes needed based on water type and similar to katana, reducing doses wont change anything except the effectiveness!

That soil mix has a quite high nutrient content so you wouldn't need to add our grow nutrient so soon next time round (if you stick with the same soil). I wouldn't recommend halving the dose on katana though you need the correct dosage to stimulate the root development effect that this product has. If your plants are still suffering, a foliar application of sumo boost can work wonders and realy bring the plant back around. Lovely structure on those plants though! Thanks for choosing SHOGUN!
