Miracle grow for veggies

So im using miracle grow veggies for my veggies. It says its supposed to last three months, but im starting to question that, within not even a month my tomatoe plant runoff was reading 300ppm! Seems very low. My aroogala also is having deficiencies. Next time I water her I will check ppm. It seems to not buffer either. It may because my aroogala is in a small pot, but my ph is reading like 7.2ish. My aroogala is having phosphorus deficiency and some weird white things on it. I put leaves on top of the soil to hopefully amend the ph issue. Whats your guys experience with this soil. Im not looking for top notch soil for my veggies, but do you have to do things to make the soil a little better, idk. What do you guys think? I can take pics of my aroogala when I get home. I tried doing a flush with ph adjusted water, but that seemed to do nothing and may have caused them to be more purple .

Yeah, all pre fertilized potting soil instructions must be taken with a grain of salt. Plants differ in their uptake needs for optimal growth. But they have to pretend that one formula fits all.
Good news is cannabis is a weed, by definition able to handle distinct differences in environments and survive, even thrive.
That's not so true with herbs and veggies...

My tomatoe plant looks great now after giving her a full dose of the fox farm trio. Went from looking sickly to wow. Watered her today and ppm were down once again to 300, so I gave her another full dose. We will have to, at this rate she will be getting fed all the time . My pot plants were at 500-600 ppm, so I will just let them slide until another watering to give nutes. Ya, there such a lier with 3 months, mabe plants that don't eat that much, but not a tomatoe. They are ferocious eaters like pot. Mabe even worst than pot. Idk how photos are, but autos use a little less nutes.

What about ph buffing? Does miracle grow buffer? I dont seem to see that, but just wandering what you guys think.

You also need to take in consideration the date that soil was bagged and not the date you purchased the soil.

Cannabis is not a weed, it is an annual, dioecious, flowering herb and is a genus of flowering plants in the family Cannabaceae.

Cannabaceae is a small family of flowering plants; about 170 species grouped in about 11 genera, including Cannabis (hemp, marijuana), Humulus (hops) and Celtis (hackberries). Celtis is by far the largest genus, containing about 100 species.

Cannabaceae is of the rose order (Rosales). Members of the family are erect or climbing plants with petalless flowers and dry, one-seeded fruits. Hemp (Cannabis) and hop (Humulus) are the most economically important species.
