Problem: Leaves of big girl are yellowing and dying. After I added the nutrient I noticed the pH run off of Big girl dropped to 5.0, little girl was 6.0 and unaffected by the nutrient. I only had a half gallon of water at the time so I put (1) tsp to half gallon. Recommended light feeding was (2) tsp per gallon, so I just halfed it. Jan 13 was the first time I ever tried nutrient and this is what happened.. I do believe the pH is just way too low and it may be locked out. Any suggestions? I hear happy frog is a very acidy soil. BTW I only have the drops to measure pH so I just use whole decimals. Also I did a transplant Jan 16 into 5 gallon, watered with plain 7.0 water. Now just waiting for next water to correct pH.
