if this is the biggest problem that ive had with organics i would say im a step above the rest. ive never had an issue with organics. NEVER any nute burn, micronute probs(save for late flower) and personly i like the smell of bat poo more than synthetic ferts which smell like something u should be cleaning ur toilet or stove with. ive spokene to many botinists that say that up wont kill your biosphere. the only way it will is to apply it directly to the medium. ie. lime....... keeping it agitated while taking your readings is easier said than done. though not impossible. the only thing im asking is whats more important for a Ph reading. the sediment at the bottem or the juice that floats above it. the point of using roots organics is that it is not so refined. organics is the way to go (my opinion). its the way pots been growing since the time of the dinos. so lets keep it in thoes lines. the reason i prefer organics is simply this. go buy an organic bannana and a regular one. and taste them both. not just taste but texture. im not saying that you can get more bulk from organics than conventional. but the final product will be better. just eat the bannanas and get back to me, lol. goodtimez and thx for the response u 2.
