Do I need to add dolomite lime to Sunshine Mix #4 when growing soilless?

I would like to grow using nothing but Sunshine Mix #4, Pure Blend Pro Grow, Liquid Karma, Calmag+, and Pure Blend Pro Bloom (Soil), i.e., I will not be amending the SS#4 and only feeding with bottled nutes. NOTE: this is regular Sunshine Mix #4 and NOT the Advanced version.

My questions are:

1. Do I need to add dolomite lime to the SS#4 to offset the acidity of the peat. If so, how much per gallon of SS#4?
2. What do I pH my water and nutes to? Recall, this is a soilless mix and not a soil mix.
3. Do I need to add perlite to the SS#4 for more drainage?

Thanks

No and lose those ferts and get some jacks pro 20-20-20 use at 1\2 tsp per gallon tap water.

Yes, but I read that it runs out so people have been adding more to it so they can complete their grows. I was wondering if anyone here had experience using it.
