N til the end? Biobizz

120ppm N then adjust as needed up or down based on observing plants.. in vege you may need more, in bloom you don't need drastically less.. figure 5-10% depending on how hard you were pushing with vegetative growth. 60+ ppm P - i've seen some go as high as 100 190+ ppm K - after 200 or so with ambient co2, you may find toxicity threshold for your garden. when trying to find upper reaches, try to change 1 at a time and let it cycle for a long time befoe you decide it worked well. It can take weeks for a slow-moving toxicity or deficiency to show itself. Especially the more you hone your formula. It's about what happens over several weeks or months, not days. All of this is based on a 6,0 pH and 1,3 to 1,5 EC concentration of mix, including the above and Ca, Mg and S. you'll find a 7-7-15 or 7-8-15 o so hits these values at that concentration range. if you tightly control environement and supplement CO2, you may be able to push higher. regardless, you'll have some minor trial and error left for you as not all gardens are the same.. the same cause and effect is at play, but some variables do impact what is needed. The difference is these adjustments will be very clear and easy to make - whith slow moving progression at worst. The plant's composition does not drastically change, despite some commonly held and very confident beliefs out there. If i stay up around 120-130 i do get some 'too dark' leaves which is a sign of N building up among other things possible. if i keep it a bit reduced, i avoid it. the reduction is small. if the plant needed N at a drastically differerent rate it would be obvious, and it is not. N is needed for all sorts of stuff not realted to stem elongation and new leaves. it's in many many different components necesary for cellular growth - including during bloom phase. flushing is masturbation unless you have a major toxicity.. again, because flushing does not change mineral content of the flowering buds. when you eat a bunch of salami do your balls turn 10% salami? no, becuase that'd be ridiculous. ==> cell differentiation will have a say in that, lol. Some portion of ppl act like our knoweldge base is still limited to the 3 humors, bwahaha. funny thing is most plants of a similar type want the same stuff.. research backs this up.. all the sophistry of horticulture is a significant portion baseless. non-science based conclusions with zero testing of hypothesis let alone understaind important of a control. a total ignorance of mass amount of volatility that must be waded through to get an answer that deserves confidence.. not something you eyeball.
