AF TYPE 01

Looks like everything is going great. All I would suggest next time is tie your main cola down when it's growing to let the lower colas reach the same height. You will get a much more even canopy then. I wouldn't top an auto because with autos they can throw a hissy fit and you don't have time for them to recover before there predetermined flower cycle starts.

If they burned like this its not only ph, you put too low ph and feed together, i saw your other question and top foto, honestly you are fucked. You will get some result, but it will be pitty of what if .... First return to wet/dry , she has to start drinking. Only 6.3 ph water when needed and as much as needed. I dont believe in flush in soil, never had good result as correction tool, it works in hydro or coco, not here. With second watering add 0.25-0.5 ml of CalMag to water. When she will dry out twice pot, give her last plain watering, only then try to return to feeding schedule if it will be any time left for that. She will develop way weaker and slower, so don't screw up more.

At this stage you should have stopped the Cal+Mag and switched for Mag+Sulfur. But this will be for the next growth. And as I already recommended to you, you reached the level where you must get a pH meter and a good EC meter if you really want to improve your growth.
