Using Heavy Harvest with coco?

Hey guys, i have a nice plant in a 2 gallon with Canna Coco that ive been vegging for about a month.

I want to throw her outside for a little bit to explode and I want to use some Summer Blend Heavy Harvest.

Only thing is that the HH is pH buffered and the coco requires pH of 5.8

What can i do here?

What if i just planted the plant in the ground and used the HH on top of that soil......since im positive its not good soil anyways. Just random field dirt.

I have perlite too

does anyone have anything to say about this?

where did you find out your info on the coco ph? my nutes tell me to have a ph of 6.2- 6.2. ?

Im pretty sure the pH should be around 5.8 Thats what ive been doing and its been working great so far. But HH is made for outdoor gorilla grows and soil pH should be between 6.4-6.7
