Ph and ppm at Harvest

Hello all
This is my first grow . This site and you peeps have been the greatest :thumbsup:
I have a couple of plants ready for harvest any time now :rastasmoke:
I have 3 questions
1 - the ph of my soil runoff is around 5 :mad: .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 ?

bump...Anyone? :hippy:

but i do kno a proper flush is three x ur pot size [ie 2gal with 6gal] and by harvest in a plant with soil the leaves should be yellowing:D

A good flush about 2weeks before harvest and after that only PH water when needed, that is the way I do mine other folk have thier way.
