The problem is that all the organic compounds are still in your soil, and the microorganisms in the soil can/will eventually break them down and they could just burn all of a sudden. Just outta interest tho, why did you HAVE to feed them? Is it cos they were a bit limp? Were they yellowing or showing another deficiency or were you just feeding them for the sake of feeding them? Just wondering, cos the amount of nutes in the soil you have already is probably UNREAL. Id really recommend flushing them and starting your nutes fresh, even just cos the Biobizz range is quite acidic, so your soil pH is probably really low from all the nutes in it too, like pH 7.5 water is dropped to 4.5 with 10ml of nutes per litre, just so you know...ok end of post, hope this helps!
