Used them with adequate results. If mixed according to instructions the ph stabilized at between 6.0-6.5 which is my sweet spot , but if you mix it stronger you will have to adjust the ph.
Sturdy Stalk and Root Wizard which I also used with adequate results will have to be adjusted as it brought my solution to above 8.5!!! That WILL F..k up your plants for sure!!!
I still have some and will use it in my next grow.
