I just looked up those products. After following my instructions above on the flush, continue to use the top max and bio-bloom at the levels you have been using. I would even consider stepping them up to 1ml per liter, or roughly speaking (gotta convert to American - I'm old, lol) one tsp per gallon. After flushing and after 7 - 10 days, if you do not see improvement, consider stepping your feeding up to 1.5 tsp per gallon. Discontinue using the biobizz grow. Your plant is past the stage of needing this supplement in these ratios.
Keep in mind, all the leaves already affected and showing the claw symptom are already dead. They just have not turned yellow yet. If you want to get a good idea of the progress of your fix, wait until all of the dead leaves start showing yellow and then go ahead and clip them out. That way you are looking at only new or currently unaffected growth.
Hope this helped! Take care.
