Hello all, I've tried to search for the answer to this so please forgive me if I'm asking stupid questions.
I'm a newbie...(you'd never guess)..I've germinated 16 seeds with a view to Flood and drain. They are in 100mm cube plant pot with hydroten pebbles. I had read somewhere that you could put them into 12/12 almost immediately which I did. Now three weeks into 12/12 and they are looking healthy enough, I have picked out side shoots and they are about 12 inches tall. I am due to change the nutrients from Canna aqua vega to canna aqua flores with pk suppliment.
Right, my question is should I still change to Flores even if there is no sign of flowers yet.
I'm checking them and I know what I'm looking for as my last grow a single plant in DWC turned hermi.
Thank you in advance for any help.

For my system I use half Veg and half Bloom for the first two weeks of the transition period to flowering. Then I use only Bloom after that, wether sex is evident or not.

good answer! I agree. Are you going to flush near the end?
