Mixing Iguana Juice grow/bloom?

Hey all, I'm about a 1 1/2 weeks into my bloom phase and at this point I'm still useing Iguana Juice grow. I'm starting to get pistols popping and I was wondering if it would be a good idea to mix Iguana Juice grow with bloom I was thinking of doing a 50/50 mix, then maybe 75/25 or 50/50 then 100% bloom. I was thinking it might be better for the plants makeing a smother transition from one to the other. Good idea, bad idea or just pointless
Let me know your opinions/experiences, thanks.

I just started using Iguana juice the kind I got claims it is both grow and bloom combined my results were good but yeah I don't see the harm to answer your question lets exchange some pics and compare I will upload in the morning-SAVES
