What a colossal fuck up in horticulture on my part!
So I've been battling these brown spots basically since they grew past the cotyledon leaves and have been trimming these 'bad' leaves since they started.
Transplant, change in soil, add nutes, remove nutes, ph up, ph down, bla bla bla bla....
Found out all along it was my water ... I did use too much, or too little, but the wrong damned H2O completely ..
Canna nutes have no trace elements and are designed for hard tap water ... not Distilled or RO water ......
So I picked up some CalMag to treat the reaming 30 gallons of RO water I have (would seem stupid to waste it) and am now searching for a viable way to remove Chloramine from tap water without removing magnesium, calcium and iron. I know my carbon filter removes sulfer and other metals that aren't good, but I think the chloramine stays behind.....
Off to google ... (update good carbon filters do remove Chloramine according to google)
Too much love, caution and care CAN aparently ruin a plant.
