canna + epsom, yes, addback 33% to 100%, try more N at begin Bloom, use full strength
> does epsom salts need to be added to canna aqua flora during flower, or just veg?
both formulas benefit from adding 1/4 tsp epsom (it adds 25ppm of Mg),
the Mg level of Vega is 35ppm, the Flores is at 42ppm.. I aim for 60-70ppm of Mg...
> still have the nutrient reservoir add-back information, from the CW days
no sorry, but, the concept is that if you keep the EC close to original levels, say 2.0, you dont need to dump your res for the life of the crop
some nutes like FloraNovaBloom, work with 33% addback strength
PBPBloom and FloraNovaGrow need higher strength in the addback, approaching 100%.. depends on the res size to light size ratio too
> a bit from N deficiency, before I top the res up, every 10 days
A current experiment that is producing encouraging results is to use FloraNovaGrow @EC 2.0 when starting a crop, topped with FloraNovaBloom for all the addbacks for the life of the crop.
Using nutes at levels below 2.0 is a good idea if the plants are under weak light in the <3500fc range, as from fluoros.
I find plant can use the full 2.0 EC even small plants, IF the light is intense, in the >3500fc range, as from HPS.
good to see the familiar handles
