Oh em gee. As much as I appreciate the thought of being in the same category of Waira & Heavily Medicated. These 2, are, of whom I regard, plant dr.'s.@Waira already said it and I will attest to it as well, even as a first time grower (a noob actually) I read and saw so many issues on here with pH and when it came to simply knowing what is the actual pH IN the soil you can't beat the Accurate 8 by Control Wizard, yeah it was $44 off Amazon, but it out shines a lot of tools in a growers arsenal I think. It's helped me a lot and even now I am suddenly finding my soil pH to be approaching 7! Even after 6.4 and 6.5 feeds in very basic Black Gold potting soil! This thing is a life saver, when you get some funds, highly recommend it you won't be sorry.
Looks like you're all taken care of by the elites around here, Jedi Master @Yeatster and @Heavily Medicated and of course the talented @Waira
Oh and thought I'd add... I am following @FullDuplex feed schedule found here. You might find this useful for future grows or even now if you continue to use thetrio as I do. Pretty good explanation of when, why and how much to use of the Trio. Like Waira said the Big Bloom is more of a supplemental nute and can be used in just about every watering as it's good for macros and roots.
Take care and don't be a stranger, these forums are full answers and friends waiting to be found.
I sit back and learn.
Cheers mates, thank you!
