ok..i need some help.. i dont think im deficient, my ph is 5.8 always and im running dwc. i run the emerald harvest kali pro a and b with their king kola and also purpanator {experimental} and the general hydro calmag. light is an hlg 600 rspec i usually run at 75% due to head room i might have just timed the nutarians wrong and giving more than needed but no more than they recommend. anyways, everything was going good then i started getting curled tips that curled up and only the tip, i knew something was off so i adjusted, but now im getting slightly concerned only because im not sure what the plant is telling me now, now my situation is, more leaves are turning yellowish and some seemed badly enough burned i removed them. now im now sure if its just following its life cycle or if its locked out or deficient or whatever. roots are clean and white, res is clean. maybe i locked it out but i doubt it, its still showing growth in the buds. just turned week into 5 today. its supposedly wedding cake, has a sweet sour almost like grapefruit pineapple smell..anyways, light is about 18-20 inches from the "main" canopy the taller limbs i tied back away from the light. check out the pics and let me know your thoughts, thanks in advance ill upload pics asap
