You didn't fix anything, you actually made it worse and you've been using Biobizz the wrong way, but it's not the end of the world :)
Feed 1-4 ml/L Bio-Grow* + 4-6 ml/L Bio-Bloom + 1 ml/L Top-Max + 4-6 ml/L Alc-a-mic (every watering until pre-harvest flush)
Bump Top-Max to 4-6 ml/L in 1-2 weeks.
* Depending on how pre-fertilized your soil-mix is
Still 3-6 weeks to go.
A bit of Biobizz tips:
0. Get another nute brand that's easy to work with, that's what I did after using Biobizz for 8 years :)
1. NEVER pH anything except input water to 7.0 BEFORE addding Biobizz nutes
2. NEVER flush Biobizz nutes out to correct things - only 2 weeks before harvest
3. Biobizz reacts slowly, what you do today won't show until 1-2 week(s) later - you have to *know* what to do before you see what you have to do
4- Measuring run-off pH is not something you do in organic grows, it won't tell you anything useful - you're building a micro biome in the soil, not balancing chemicals.
5. NEVER grow with Biobizz without using Alc-a-mic
6. Don't use Biobizz if you're a beginner, it's quite difficult to grow with - personally I would only ever use it outdoors in the ground or in raised beds
