Yeah I don't buy into that organic rip off stuff mate. Them tablets I'd be careful with. Each strain needs different ppm levels. A tablet with a fixed ppm can't be enough for every strain. Buy a ppm meter for £4 on eBay and feed something like old timers organic if your set on organics and push your plants as much as you can to increase yield. Thing about a ppm meter is if you see leaf burn from over nutrients you can back off 100 ppm until you hit the sweet spot for your strain.
