Growth technology hydroponic pH.

Hi All,
I bought a bottle of growth technology hydroponic pH down but I removed the sticker to use as a plaster last year and I've lost the directions of use now I need to use it again.
When I done a Google search on growth technology hydroponic pH down it says use 1 -2 ml for 50L
Say's that it is super strong and only use one or two drops per gallon.
Does that mean one or two drops to lower it by 1 or does it mean it will put the pH to exactly where it needs to be.?
I am using Coco gold label 60/40 with canna Coco feeds.
I read that rhizotonic takes the pH to a whopping 9.?
I cannot order a ph pen for a few weeks so I have got to guess it for now.
My tap water is Hard - pH 7 but rhizotonic apparently takes it to 9 how many drops do you think I should use per gallon.?
I have been using 2 drops per Gallon but don't no if it's enough or to much.
There were about 2 inches tall 12 days ago so they are growing really well but I do not know no if pH affects the growth.?
I thought the book and I was using a fever of 3 gallons but it is only 2 gallons so I was over doing it with the feeds and there were very dark green I read that it was probably too much nitrogen so I gave them 2 ml a liter yesterday and there going a bit lighter green already.
Should I keep spraying with rhizotonic or will I be wasting feeds as I added in with the feed.
I will be greatful of any help.
Thank you.
 
Just buy A ph test kit for a pool or ph drops cheap and effective
All ph adjusters are based on your readings and water not by measure
Oh and WELCOME to RIU :weed:
 
I can't buy a pH tester for 2 weeks mate so was hoping for a rough guess until I can get 1.
MY tap water is hard and pH 7.
I have been using 2 drops per gallon and they are growing but I do not know if they would be signs if I had the pH far out.
I would not really be bothered about the pH if it was not for the rhizotonic taking it up to ph9.
Thank you for your reply and welcome msg
Cheers

Let’s try this
I grow in promix which is basically peat and vermiculite with a few additives
I do not ph my water
That means on no nutrient days I am using 8.1 and on nutrient days it is much lower but I still don’t check ph
I have literally no issues with this method
At least worth a try till you decide if you really a ph meter

Lol liking the pic.
I'm growing in Coco mate so need to pH.
I started using cannazayme after the second week.
Think I will give various drops a gallon until holidays finished for pH meter to arrive.
That plant looks awesome.
I have 3 bags of All Mix Biobizz but I've never grew in soiland wouldn't no how but it's great that pH is not an issue in soil.
Thank you for the reply

Always good to have a dropper pH test kit on hand.

personally that’s all I use is the droppers and aim for 6pH.

personally I use growth technology pH down and NEVER use it neat Into my nutrients.

I always dilute it 10-20ml in a 100ml bottle and add water into it.

Then a quick splash into my 25L mixing canister drops me from 7.5 to almost 6.
