bump aqua you can hit em with some N but the growth centers will be a brighter more limey color thats natural.
Yes you should, like said above get some fish man! that will rock and is pretty avail. also as stated above most of the nutrition is washed out by how your watering so you need some liquid food to feed em right away and give it time for your top dressing to work. Fish is you friend....helpful tip water in your top dressing with some SST or compost tea to really get it rocking. And dont be in a rush, your getting back onto the right track, now make thought out moves to get to where you want to be. I top dress every ten days or so and feed weekly with fish plus doing some super water(compost tea, alfalfa kelp tea, malted barley tea). I try to do something different every third watering.
Also be sure to remember what aqua said about watering!! you want to correct your PH and then stop watering until runoff, just keep the soil moist and water to run off just to check your PH n stuff.....
mancorn, you rock the Rhodales thermophilic recipe? I have really really been wanting to try it!! This year i will! how do you ferment? I use alfalfa seeds and make sprouts then blend up and make a SST, also i like to use alfalfa meal in a tea and a top dressing. Old school Clakamus Coot stuff right there
