I think they dieing from root bound!

I think u are correct about ph issues. Just realized I hadn't calibrated my meter in almost 2months since I bought it. Just ordered some solution. Big clue was that I tested my tap water and it read 6.5 which it has never been perfect. It was always mid 7's. My guess soil is high alkaline now. That might explain the coloring issues on the leaves.They say vinegar can get it back down to the rt level ph if that is the case. Would u say thats about rt?

Sounds about right, don’t recall this thread but good ph is good, not good ph not good.

lots of things can be used for ph down. I like vitamin c powder best then citric acid (cheaper). Never used vinegar to be able to comment on it.

hopefully the ph of the medium not to far off it won’t come back easily. Had that happen to me and it’s not fun. As a matter fact, one was a banana dance too lol. Freebie from attitude?

Do not use vinegar acetic acid is a herbicide, it may work but will have negative effects over time. Citric or phosphoric acid is much better.

U hit it on the head! Freebie from attitude! I usually use lemon juice for my ph down but have been reading that it kills gd bacteria as well as the bad stuff. Once I get my ph calibration buffers today I will know how far off I am. Then the fun begins. Just found nice video on how to make the buffers. Super cheap. Wish I saw it b4 ordered the expensive crap. Especially since they say calibrate your ph meter every 10 days for accuracy.

I will keep looking in to it. Thanks for input. Citric might be the way to go. I already use it for my diy co2 set up. And come to find out thats what they use to make the ph calibration buffers. 4.0 -7.0- 9.0 citric monohydrate and potassium citrate is all it is.

then add some die and charge a million dollars a bottle

No updated pics. Ran out memory on my phone. They look alot better then they did originally. I calibrated my ph meter and all of em are ph'd perfect 6.2-6.5ph on runoff. I find my only issue now as someone pointed out is I can't truly flush nutrient rich soil. Plant on left and the middle are at 750ppm and the one on the rt 950ppm runoff. Can anyone tell me what they would do next or should I just chill and roll wit it? I can just feed them less and give them the rest of the proper ppm's for their age. My biggest concern is that I have no control over the nutes its being feed. FYI ffof started out the gate super high of 4000ppm then dropped to about 2000ppm in 4weeks. My newer plants that are in week 2 flower have runoff of 1200ppm rt now. Evidently thats normal for ffof. They say don't go by the runoff of ffof. Any help guys would be appreciated.
