Hello all

This is my first grow .I have a couple of plants ready for harvest any time now
I have 3 questions
1 - the ph of my soil runoff is around 5 .I have been feeding with a ph of 6.8-6.9.
my question is,how high can i safely ph my water to compensate for the low ph in my soil?
2 - the ppm in my soil is very high as well .I am now flushing the plants.
What kind of ppm do i want to see at harvest time?
3 - from what i've read here ,you want to start flushing a week to 10 days before harvest.Depending on a lot of factors that could be anywhere from 3 to 6 feedings (flushes) .I guess that comes back to question 2. How many flushes before harvest or what ppm should i be looking for ?
