Welcome to the forum
@MR-GREEN666 nice to have you as part of the family
I myself only use Canna and have been for almost 2 years great product apart from the $ easy to use
as canna is a all in one but just use more as you go in to flower i recommend you use more of part A in veg and more of part B in flower so let's just say they recommend using 100ml of A and B use 110mls of A and 90ml of B in veg and the other day around in flower
as in Veg you need nitrogen
and if flower you need more phosphorous not a huge amount more but a little more but the change of 10% will be a nice start remember each stain is not the same so its hard and what ever canna recommend down it buy at least 10-20% and your plants will be happy if your running them with hard water and you are dealing with hot weather i recommend flushing once every 1-2 weeks with a 50% feed to bring the levels down (ALWAYS CHECK YOUR RUN OFF FOR PH AND EC ALWAYS!) if they start to go up its time to flush
I recommend rhizotonic so much that shit works really well smash them at the start with the recommend 4ml per liter or 20 ml per gallon and you will be rewarded with fat strong steams great root systems and a over all happy plant if you need anymore info just post and i am sure some of the others that grow with canna will help if your stuck just inbox me and ill message you back as soon as i am free
once again welcome to the forum i hope you enjoy your stay and i recommend not posting a how much will i yield post or you will be hammered plus its almost imposable to tell
