Mixing products with a high concentration of PK should always be done with care and knowledge. As there is a high risk of over-fertilisation you should always check the EC of the final nutrient solution.
Atami does not recommend using Bloombastic and Rokzbastic at the same time. Always start with Bloombastic to boost your flower formation and maturation. Towards the end, during the ripening phase, switch to Rokzbastic.
By using Rokzbastic at the end, you will boost the results of Bloombastic, thanks to its compacting and hardening power. In addition, the sugar content, natural aromas and flavour of your harvest will be boosted.
