can somebody post the pH lockout chart that shows at what pH certain nutrients get locked out? i have what looks to be a nitrogen deficiency on one of my ladies and phosphorous on another, i don't know but i think it may be an issue of pH i'm only 3 weeks into flowering and i'm seeing a lot of yellow, trying to fix/save as much leaf cover as possible any help is greatly appreciated

i have the same problem, so what did you do for yours? are you in pots?
if i have low ph soil , can't i just flush 6.5 ph water? some say flush with 7.0ph water
 
ya if you have low soil ph flush with lightly higher ph water around 7.2.. If your soil is too high water with more basic (6.2) until it improves. At least this is what i do. I just do this and check the ph runoff until its in the correct range. Just be careful about flushing with ph that is more than a point off, can shock ur babies.
