Figured out deficiencies now looking for the best mix to fulfill them

Good morning,

About 2 days ago I noticed that my soil was still very acidic so I was getting lack of nutrients to my plant. So I figured a way to balance out the Magnesiudecalciumr deficiencies added some micronutrients and some live organisms. And after that I am now stuck with the phosphorus and potassium problems. I don't believe that potassium is a problem however the deficiency in phosphorus is. But adding a nutrients with just phosphorus in its is proving to be difficult and I am on a very tight budget

At my disposal I have acquired the bembe foxfarm I also have the Big Bloom foxfarm that I was using as a foliar spray. Now I'm trying to go as little as possible at first but the forliar spray is wworking temp.I'm just trying to figure out a way to add the phosphorus without risking a toxicity and potassium.

In my lineup I have Advanced grow, hrygrozyme , liquid Karma..

I am wondering if it is okay to mix the bembe in with them they have the lowest amount of potassium if any.

Or if it would just be best to throw it in the four-layer spray and go from there

How old the plant?

Clone.. I've had her for one month she's 17 inches tall by 18 wide

You said the issue is the soil is acidic. Seems like the solution is obvious, and a basic, aka PH UP.

Easiest way to fix the PH problem is to recirculate the same water though the pot while correcting the PH of the water between cycles. If the PH is way off you can over-adjust the water to minimize the number of cycles required. (if the soil is at 5.0 and you want 6.5, you can run 7.5+ water though until you read greater than 6.0 on the overflow.
