Tigerbloom PH4?

I just tested the ph on a batch of tigerbloom I mixed up and according to genhydro ph test ph was around 4 (bright red/pink) my water is testing around 5.8 this winter.

Is tigerbloom always that acidic out of the bottle?

Yes.

I made a thread way back doing a comparison of a few different flower nutes. I found that the Tigerbloom was the most acidic of the bunch and I stopped using it right there and then. I was burning my girls up at week 3 of flower and I had no idea why.

Afterwards I used only the Grow Big and the Fox Farm powders for flower. Never had a problem since.

I guess you can also use just 1/4 strength of what they recommend. That stuff is very very strong.

I use Tigerbloom for flowering and it can definitely burn your leaves if overused. I was using high amounts of Fox Farm's Grow-Big with no negative effects during vegetation so I slowly started the Tigerbloom at its suggested amount and it burnt some leaves. This was even with adding ph-up to bring the water to 6.5-6.7

I've since lowered the amount I add to about 12-15 mg/gal depending on stage of flowering and no more burn.

I'm trying to research something better.
