hi all..thank you so far for your help..my plants are getting back into shape after i feed it only water ph 5.2 and some hydrogen peroxide.
now im back using my big tank with 280ppm..the plants sucked the nutes down to 260ppm
and getting a little greener, ill wait a week and then start adding 50 ppm as a step. I still hope there is some place where i can find GRAPHS for diff plant behaviours...like nute uptake vs time...or water uptake vs time/growth..etc i found a table for
light in lums vs bulb hight
