Canna Rhizo during flowering

Can i u use canna rhizo during the 5th week of flowering because my plants have been under some stress lately, first of all they suffered a little bit of nute burn, then heat stress, then they suffered a blackout for 3 days during 4th week of flower! They look a bit ill but im sure i can rescue the crop with some T.L.C

Ive heard people say canna rhizo helps plants when they are stressed but can not find any clear confirmation weather i can use it during the flowering stage

Thanks growers

You can use it no problem in flowering, although canna recommends you keep the dosage low.
