Ahh Mr Jorilla!
Well after yesterdays revelations - I had to get on my white coat and do some serious lab testing and re-calibrations
Although i scoured the Canna forums, i could not find that info on EC you kindly put my way.
Results of the (bathroom) Lab tests (after very carefull calibration and re-calibration)
1)
Water: Tescos Bottled
PH: 6.3
EC: 0.1
2)
Same Water: with 2ml per litre rhizotonic
PH: 7
EC: 0,.1 (the fishy rhizo does nothing to the EC)
-- then PH'd back to 6.3
3)
Same water with rhizo: Added 1ml A&B
PH: "A" did not change it - "B" dropped it to 6.2
EC 0.5
(this was all for a foliar feed)
.. So my slight concern being that to get to an EC level of 0.8 with the water i'm using - i will need to add about 1.5ml per litre of A&B - which "feels" a little strong at this stage - but is it all about the EC?
Whats your thoughts on this Jorilla buddy
