I've started the EI doing this morning, using James' "All in One" solution. Dosing will be daily, before lights on via a dosing pump (or at least it will be once the replacement motor arrives for it

- for now its dosed by me

).
Thanks to London Dragon for running the numbers through NutriCalc, and for the number crunching on his AllInOne thread which helped alot !
😀
KNO3 - 5.22g 3 times a week
K2SO4 - 2.4g 3x/wk
KH2PO4 - 1.48g 3x/wk
MgSO4 - 13.53g 3x/wk
Trace - 0.91g 3x/wk
The pump doses 40ml / min so will be timed on for 1 min per day, which is the minimum the timer will allow. I've made up a 1400ml solution which should last for 35 days, so I'll replace it every month. Mixing for 35 days also means you can just multiply the above amounts by 15: (( #g x 3) / 7) x35 = #g x 15
So added to 1400ml of RO water is:
KNO3: 5.22g x 15 = 79g (rounding up)
K2SO4: 2.4 x 15 = 36g
KH2PO4: 1.48 x 15 = 23g
MgSO4: 13.53 x 15 = 203g
Trace: 0.91 x 15 = 14g
E300 Asorbic Acid: 1.4g
E202 Potassium Sorbate: 0.56g
It'll be interesting to see how the solution settles after 24 hours, as I wonder whether it'll need mixing up before each dosing which will make the pump use tricky.
Any thoughts on all this would be appreciated, as I'm dabbling in new waters here !

Cheers
