When talking about ph, i use advance nutes that are supposed to be Ph perfect. Water going into the nutes (part A and part B sensi grow) is well water at 6.2 ph. After mixing nutes i get 5.8 ph. What is the absolute best ph for feeding? Been keeping the mix at 6.2 by using ph up because when the big flush comes 2 weeks before harvest water will be 6.2 from flush to finish. Any thoughts or recomendations for optimal success?

Generally speaking, soil 6.3-6.8, coco or soiless 5.8-6.2. Sorry im not familiar with the ph perfect advanced line up.

So i am in soil. Happy frog so im am guessing my ph could be a little higher that 6.2. I do understand many factors as far as other minerals in base water as well water has varients

Whata your ppms? Which nutes are you using? You need to be 6.5 to 6.8 in soil. If using salt based nutes, you need to follow the flushing schedule to keep salt build up out which will crash your ph and lock you out.

I haven’t checked ppm out as this is only my second photo and third plant ever. Auto was a disaster. Here are the nutes
Not using all been using grow A and B with cal/mag and B52 in veg and Bloom A and B with cal/mag,big bud,B52 and overdrive. I am in soil and only aintaining 6.2 so im guessing i need to up ph to be abke to absorbe nutes better. Delivering feeding at 76 degree f as this is the temp in the grow.

Not using the full line yet but i am following guidelines for each that i am using and have been told not all flovors are needed?

Plant looks pretty good to me. I would say what you’re doing is successful and don’t see any reason to change.

Thank all so much on this topic. Every time i think up what some of you may think is a silly question you all give solid replies regardless and it make me thrive!!! Growing with all of the support i get here… how could anyone go wrong?

Here is a chart that may help. In soil I usually shoot for 6.5 going in, and everything works out fine from there. A little bounce from the sweet spot is nothing to worry about.

I believe @kaptain3d has used advanced nutes and may be able to assist

I think that those automatic ph nutrients are designed for the hydroponic ph range. They will pull the ph down as the time delayed ingredients activate.

I think @Cap_Ron
Uses those nutes as well! I think!
If not he will have some fantastic information for yu!

All I can say is that if you’re using the PH perfect lineup, don’t worry about PH. It will do it’s thing and it works really well.
People that have a hard time with the PH perfect are the ones who tries th PH their feed anyway… Useless paying a premium for a feature you’re not using if you PH anyway…
If you look up Advanced Nutrients website, they specifically mention not to PH when using their PH perfect products. 
And I believe @Hellraiser has used those nutrients too…

You’d be better off not adjusting the pH. The idea of the pH perfect technology isn’t necessarily to land your solution at the exact pH level that soil grows typically call for, but to make the nutrients available to your plants in a much wider pH range through multiple chelation processes. In other words, when using those nutrients, you can ignore the charts that show exactly which elements can be absorbed in different pH ranges. With those nutrients, all the elements can be taken in by the plants through a very wide range, like from 5.0 to 7.5. I’m not by any means saying you’d want to be that low or high, but according to Advanced Nutrients, it would be ok. I’m in a soil grow right now, and I haven’t checked pH in 2 months. I know the input of my solution is around 5.6 to 5.8, and I don’t check runoff pH unless there’s a problem. I check runoff EC every other day, but with the pH perfect nutrients I almost never check pH.
On a separate note, it sounded in your post like you might be using the Grow A & B and also the Bloom A & B together. Did I read that wrong? You’re only supposed to be using the Grow A & B during veg and then stop using it and switch to the Bloom A & B for the flowering stage.
Another thing is that you said you’re using Overdrive. That’s a late stage bloom booster that should only be used in the last 2 weeks before the flush (if you choose to flush), and it should also be used sparingly as it has a very big impact on your EC. For example, it raises EC by almost double the amount of Big Bud, Using it early in flower can throw off your nutrient element ratio, and cause phosphorus toxicity.

I only use grow in veg and bloom in flower i did use overdrive a little early at a reduced rate once then I found the chart pdf and will be following that. These (big bud and overdrive) were recomended by my local grow shop and i don’t think i understood how to use them. Yes i will be flushing then water only for the last 2 weeks. Yesterday stared week 5 of bloom so i will o ly be usingBig Bud through week 6, overdrive weeks7and 8 then flush as this is sativa (10))weekish
Again thank you and all those who help. I spend an hour or two a day just reading and asking question since may 23 and this plant #2 is the result of all of you folk knowledge!!
