Yeah generally wanna keep it around 6.0 or 5.8

I was thinking it may be pH. It was right at 6 so I decided to check my meter. I’ve had it 8 days past the return date and it quit working! When I try to calibrate it, it calibrates to 6.86 no matter which solution it’s in. It even reads straight vinegar around 6!

I guess I’ll pick one up locally so I can get it tomorrow.

Theres no need to cut back on Jacks 321 program run jacks full strength from seed to harvest I germanated my seeds in full strength jacks. PH I mix a gallon at a time at 6.5 (top feeding) for about the first three days the PH goes 7.4+ keep adjusting it down and it starts holding.I use a air stone to keep the nuets circulating in the container.


I bought a decent pH meter and the ph was over 7! I don’t remember now but I think 7,2. I’ve started bringing it down so hopefully things will improve quickly.
