Mix:
A=4ml/gal
B=4ml/gal
Tigerbloom=3ml/gal
Creates a nice early flower 1-1.23-1.69 ratio (300ppm, which sounds about right). For me, that would be a nice ratio. But, others like other proportions.
If you reduce TB to 2ml/gal, that's 1-1-1.67, (275ppm). That might be better if you're just in transition right now. (If you increase TB to 4ml/gal, that's 1-1.43-1.71, 325ppm. That might be good in mid flower.).
My only concern here is that you used hydro nutrients during veg. But, you're growing in soil. MG's potting mix is charged with slow-release synthetic nutrients. So, using synthetic hydro nutrients wouldn't be much different. But, Tigerbloom contains organic sources of nutrients. I'm not sure how hydro nutrients would play with that.
If you omitted TB, you could use A=2ml/gal, B=8ml/gal for ratio 1-1-2.88 (282ppm). I don't think you can raise P much with those two bottles by themselves. 1ml & 10ml is 1-1.43-3.79. That's kind of high K. I never go that high. Not sure how that would work. Those two bottles should have a schedule for flower. You could just follow that. But, maybe half-strength (often schedules are overstated that way. If you mix anything I mentioned above, you should verify the ppms with a TDS meter. I'm just calculating them. But, product labels are *minimum* guarantees. They can be stronger.
That's ironic. Five years ago I saw a bag of Kellogg Cactus torn open at Lowes and *instantly* thought, "that looks perfect!" I've wanted to try it for these years. Just 3 weeks ago I sprouted two seeds in it. My grow journal is
here. (<<link).
I've been finding that cactus mix to be N deficient. I've been pushing N higher (as a proportion) than I *ever* grow at. I can almost see the plant's leaves green up with more N, then go back to a limey/yellow color on a daily basis. It's like the *medium* is N-deficient, and drawing it out of the plant. I've never experienced this before. (Could be ph. I'm not ph'ing anything. I have my own light, airy soil mix which works perfectly. I have the nutrients dialed in. I haven't ph'ed my water or nutrients for 5 years. So, I'm trying to make this Cactus work without having to go back to using a ph pen. I want it to be simple, workable for anyone who, on a whim, decides to grow. They shouldn't have to have a ph pen. Nobody does that with their houseplants! But, sometimes I think the problems I'm having with N are ph-related. I think I have it dialed in now. I just transplanted using weak nutrients. I'll go back to feeding in a day or two. See if I can manage the N.).
The one thing I like about this Kellogg Cactus mix: it's well-draining, fast drying. I came from growing soilless using hydro nutrients, feeding every 2 days. I created my light airy soil with that same style in mind. So, this cactus mix fits my style very well.
Anyway, it's odd to find someone planning to use Cactus mix. As far as I could tell, no one's ever tried it. Now here's a second person preparing to use it.
