*Power Africa's bottom leaves
*two weeks flowering
*50/50 Happy Frog and Ocean Forest with added perlite, 3 weeks since 7 gallon transplant
*nutes fed once mid vegatative (which burnt her a little), none since transplant except 1 feeding of Epsom Salts (1 tsp) a week and a half ago.
*using tapwater that sits out for at least 24 hours, usually more... PH of water is about an 8 using tho cheap liquid drops.
*I don't have a ppm meter

Looks like a cal/mag deficiency probably caused by your high pH, which stops the uptake of certain nutrients. Nute burn would have started at the very tips of the leaves, which I don't see. Your pH of the water going in should be around 6.4-6.5. IT'S NEXT TO IMPOSSIBLE TO GET GOOD RESULTS IN THE END WITHOUT A DECENT pH METER- THINGS WILL ONLY GET WORSE AS YOU GET LATER IN FLOWERING. So, buy a decent pH/ppm meter because you will have to eventually anyway.

What do you recommend for a organic PH down?
