Are you using real PH down? Home products such as vinagur and lemon juice will not hold a stable PH for the same amount of time as real PH up and down. Also, 5.1 is fairly low and can lock out some nutes. The lowest you want to really go is 5.3IMO.

BlueBear Reviewed by BlueBear on . Why isnt my PH level more stable? Well I lower it and it jumps a whole point by the end of the day. Ive been trying to get it down to about 5.1-5.8 and it seems everytime I check it goes futher up lol. Is this normal? Its only an 8 gallon res and Im just starting and Im unsure why this is happening. My Journal http://boards.cannabis.com/showthread.php?t=89797 Rating: 5
