Normally, Miracle Grow potting soil is buffered to a ph of 6.9...usually not a problem.

Last week I bought 2 bags for transplanting and the ph was very low 5.8 - 6.2

It killed 6 vegging plants. I added lime; trying to nurse 6 more back to health.:wtf:
Dutch Pimp Reviewed by Dutch Pimp on . HELP! leaves turning brown Hi i am a first time grower and i am having problems with my plant i am not sure if its from over feeding or what i am using 24-8-16 mairical grow and i feed my plant once every 4 to 5 days i usually water when my gauge is at 1.5 at the bottom of my pot and the top soil is completely dry. it seems like its only the fan leaves that will turn completely brown and over time it works its way back until the leave is pretty much gone.. the other leaves only get it at the tip but it don't go any Rating: 5
