It’s my understanding CocoLoco prefers water ph’d around 6.1
That said, I’ve only used it for the last two grows. My first grow, I had three autos in 10 gallon pots. 2x purple haze and 1x orange diesel. 1 purple haze produced 9 oz and the second 3.5 ozs. The orange diesel produced 4.5 ozs.
I’m half way through my second grow with it but recently have well water issues, so my results will be off for sure, which is too bad cause I was trying my luck in 3 gallon pots. It’s much easier to water effectively, but like I said, my water is shit now from sulfur.
One thing I’ve had issues with all along is keeping the ph down. Almost always peaks around 7.0 nearing week 4-6. That said, it helps to feed every other time, but I like to push my plants by feeding ph’d water to see where they are at each time (every two days) then immediately feed ppms according to read to keep them fed.
Hope this helps!
