mine are about 20 days and have a few nodes, some ready to clone, after the first 10 days of 'seedling(slow) growth' they are hitting about 1/2 inch a day, in the willd some strains have been measured to grow 6inchs a day !
hi all , big bang is not a good outdoor strain imo, having flowered them twice now... they are a 10 week strain through and through , i will be growing some early girls
the normal canna range is expensive but second to none imo , i use the lot , veg ,bloom, rizotonic , cannazyme , pk13/14 ,boost acc, and flush in canna pro soil.
their site has a very handy nute calculator.

i thought if i did it half strength it mite be npk 2/10/5
if the full npk was really 4/20/10,,
is correct, i use all canna soil/nutes...but not their bio range , thats is poor.
