thats why they have a solid burn on the tips and the 'claw' elsewhere.. the heat and rapid drinking pulled the nutrients from the roots quickly, and over feed them.. then, only mostly water was being absorbed because the eco system wasn't able to make the nutrients available fast enough.. so they are hungry, over saturated with photons and not enough food to convert the photons into biomass.. look at the claw, tips, saw blades and cupped leaves.. their not yellowing or Brite lime green.. they dont have blotches
