Hey ddawgg i had the same problem with Fox farms Ocean forrest recently. The soil was way to low on ph and my plants were burning up with only 1/4 to 1/2 strength nutes. Just the soil straight out of the bag was coming out lower than 6 in a runoff test with 6.5 ph water. I went to home depot and got some natural lime, its little brown pellets that dissolve fast in water. And after watering them with about 1 to 2 tablespoons in a gallon of water they started to come back up in a few days. What i do now is just put a couple tablespoons in half a five gallon buckets worth of dirt (FFOF) also with the pearlite in there and add water and mix it up. The siol has been right on since then and i have not had any other lockout issues and everything is growing great!
