still havent checked the run off on my girls but i did do a check on some recycled soil i have. i used water straight from the tap at 8.5 ph. filled 1 gal. pot till i had clear run off and ph was 6.3. did my usual ph down method bringing water down to 6.8 and the run off was still 6.2. gona have to set aside a day to bring the girls out and give them a good flushing and see how things are. hell i could have been mistaking my problems. maybe i was dropping my ph to low trying to fix. now i have the proper tool for the job i will know.
