Thanks guys I'm overwhelmed with the responses, I'll start with my nutrients @budelee I use 2 litres to each plans and I've been feeding them 4ml of canna A and 4ml of canna B along with 3ml of canna calmag agent and getting around the 800-900 ppm mark always making sure I'm at ph5.8 on their last feed they had 2ml of rhizotonic added and was getting a reading of 900-1000ppm and then ph'd it to 5.8. I've tried ordering optic foliar but I can't find it anywhere and when I did it was out of stock @hippy71 this is the foliar spray I'm using at the minute it's called mother pukka rocket fuel here's some pictures, I've been using as recommended on the bottle.
I've got a brand new misting bottle as well to make my own spray if I need to.
