Dead on advice: dude you have learned a lot.

Right on!

Bumping up to 6 or even 6.2 can be ok. Look at the chart Ph is one way to give exact nutrients. Like if you are lacking one by raising the Ph you can increase one nutrient over another one.

Like Ph of 5.8 there is no real Mn uptake, Fe is reduced and so it B & P & MG. By playing with the Ph you are playing with fire. If you do it right you can fly through a grow and have results others can only dream of.
