It would be a lotta a lotta hassle flushing them because theyre in a loft and transporting them down would be very dodgy. I have been checking the pH through the grow and its never went below 6.5 or above 7. when they were getting overfed, im really unsure of how much they were getting, i was just pouring a bit into a jug and mixing it, sometimes it was a lot but sometimes it wasnt that much so i may have gotten lucky this time. I fed them today because they needed some water and i wanted to give them some bloom nutes because they are two weeks into flowering and they hadn't had any. now i have the measuring capabilities i will be fine from the start of the next grow, as of this grow il just keep the nutes level fairly low from now on just incase. thanks again for the time and help mate cheers.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!
With all nutrients its not how many ml's to put in, its the part per million or PPM you need to concern yourself with. Vegging plants will require from 400-1000 ppm depending on size and flowering requires from 900-1500 ppm stage dependant.i have been using biogrow through my whole grow but i think it was as much as 10ml per lite as i wasnt measuring. i now have droppers and my girls are two weeks into flowering, how much ml per litre should i use of both BioGrow and BioBloom? +rep for any help, thanks
