Thanks for the replies everyone. Regarding the potency: it's getting the job done, but it sure ain't medical grade! Amstron, I think you may have turned on the lightbulb for me. I've "flushed" the plants maybe twice in the 3 months they were growing but I'm pretty sure I screwed that up due to using too little water to efficiently flush salt deposits and the like. I've been using nutes throughout the plants life cycle; Hesi TNT Complex for veg and their Bloom Complex for the first 3 weeks of flowering and I added their Phosphorus plus to the bloom there after. I haven't heard of many folks using HESI products on this website so maybe there's a reason for that. Thanks again for the responses! Much appreciated. :thumbsup:
