im in soil trying to be organic, no real need for ph adjustments etc or flushes and all that, don't get me wrong I get problems, but the worst is either of my making ie enviroment or maybe a bit of Epsom salts, it appealed to me as you don't get salt build ups and lock outs etc, as much, just look after the soil and let the soil look after the plant, though im only scratching the surface of it all, thought id get to learn how it goes in soil then I will proberly go to undercurrent dwc, I keep saying it but haven't taken the plunge yet, im not a green finger sort of person more like bumbling from one grow to the next, trying to learn as I go but I enjoy it, pulled 17.5 oz from 5 royal queen blue mystic last time not fantastic by some peoples standards but I was happy, done those a few times but have moved on to incredible bulk got 10 of them in flower now, looking good, 10 pineapple chunk in veg (wished id read more on them first) 2xsilver haze and 4 amnesia, some in veg n some in flower with the bulk, popping more bulks tomorrow to replace the ones in flower though im a bit late so that tent will be empty for a bit, once theyre all done ill proberly try hydro, just sorry I cant give you any advice with the coco. don't like the sound of the flies and that is that common with it then? id go with the lime pellets though just make sure you get the dose/amount right and id defo get a reliable phpen from what ive noticed its vital, and I reckon your right about the ph swing to get the better range of feed taken up
